Types of Cable Connectors

Different cable jointing applications require different connector materials and connection structures. WISETREE provides four main types of electrical cable connectors, allowing customers to select products according to conductor material, connection method, and project requirements.

For copper-to-copper cable joints, explore our copper compression connector series. For conductor transitions involving copper and aluminum, review the bimetallic connector range. If the installation requires bolted connections, the mechanical cable connector series provides additional options. Material compatibility and electrical ratings must be verified for the selected model.

Cable Connector Specifications & Selection Guide

Selecting an electrical cable connector requires more than matching its nominal cable size. The connector must accommodate the actual conductor material, construction, cross-section, installation method, and joint dimensions. The following specifications should be checked before ordering cable splice connectors.

For non-standard cable jointing applications, provide the conductor details for both sides of the connection. A dimensional drawing is recommended when the connector must fit a specific joint enclosure or installation space.

Available Cable Connector Sizes and Product Dimensions

WISETREE offers multiple cable connector series with different dimensions and conductor-size ranges. The following tables show published examples from our copper crimp connector and mechanical cable connector ranges. They are provided to help customers identify suitable product families before reviewing the complete model specifications.

Copper Crimp Connector GLC – Available Dimensions

The GLC series is part of our copper compression connector range. The published product table includes GLC-16 through GLC-400, with dimensions A, E and L. These dimensions should be checked against the product drawing when selecting a connector for a particular conductor and crimping system.

For the complete dimensions and model drawing, see Copper Crimp Connector GLC. Other copper cable connector series, including GTY, CDC and CLK, are available within our copper connector product category.

Mechanical Cable Connectors BMC – Conductor Size Range

The BMC mechanical cable connector series provides bolted connection designs covering different conductor cross-sections. The published range includes models for 10–35 mm² through 1000 mm², with different body dimensions and bolt configurations.

These values are from the published BMC product table. The complete drawing also specifies L1, inner diameter, and bolt AF dimensions. Review Mechanical Cable Connectors BMC for detailed dimensions. The compatible conductor materials, conductor classes and application ratings should be confirmed separately for each model.

Reducing and Transition Cable Connectors

Not every cable joint connects two conductors with the same cross-section or material. Where a project requires different cable sizes, reducing connectors or specially designed mechanical cable splice connectors may be appropriate. Where copper and aluminum conductors must be joined, the selected connector must provide a compatible transition between the two materials.

For reducing cable joints, never select a connector using only the larger conductor size. Both conductor insertion dimensions and the approved connection range must be checked.

Compression vs. Mechanical Cable Connectors

Compression cable connectors and mechanical cable connectors provide different methods for joining electrical conductors. The appropriate design depends on cable size, installation tooling, conductor compatibility, and project specifications.

Compression connectors are commonly selected when compatible crimping equipment and approved installation procedures are available. Mechanical cable connectors may be useful for applications where a bolted cable connection is specified. Neither type should be treated as universally interchangeable. The complete connector and installation system must meet the relevant project requirements.

Cable Connector Materials, Construction & Surface Finish

Material selection directly affects conductor compatibility, electrical contact performance, corrosion considerations, and installation requirements. Different electrical cable splice connectors are designed for different conductor materials and connection structures.

When ordering aluminum cable connectors or bimetallic cable joint connectors, specify whether the conductor is solid, stranded or sector-shaped. Also identify whether the cable joint will be installed inside a heat-shrink, cold-shrink, resin-filled or other approved joint enclosure. The electrical connector and cable joint enclosure must be selected as compatible components.

For projects requiring a particular material grade, coating thickness, conductor compound or corrosion-resistance specification, include those requirements in the RFQ so the available connector design can be evaluated.

Applications of Electrical Cable Connectors

WISETREE electrical cable connectors are intended for conductor joining requirements in power distribution and industrial electrical systems. Different applications may require different cable connector structures, dimensions and technical documentation.

For projects involving both conductor joining and cable termination, customers can source complementary products from our cable lugs range. For electrical grounding and protection components, explore lightning protection and earthing products.

Custom Cable Connectors & OEM Manufacturing

Standard electrical cable connectors may not match every conductor size, connection geometry or installation requirement. WISETREE supports custom cable connector inquiries based on technical drawings, samples and application specifications. Proposed custom dimensions and structures are reviewed according to manufacturing feasibility, material availability and the applicable technical requirements.

For a custom electrical cable connector inquiry, please provide a two-dimensional drawing or reference sample where possible. Identify the conductor material, conductor cross-section, required dimensions, installation method, applicable technical standard and estimated order quantity.

Customers requiring a replacement for an existing cable splice connector should also provide the original product dimensions and installation requirements. Model equivalence should be confirmed technically rather than assumed from appearance or nominal cable size.

Quality Control & Applicable Standards

Electrical cable connectors form part of a conductor's current path. Correct material selection, stable dimensions and an appropriate installation process are therefore important for dependable electrical connections. WISETREE performs product inspection before shipment and can review additional project documentation requirements during quotation.

Some cable connection projects specify IEC 61238-1 or applicable parts of the IEC 61238 series for compression and mechanical connectors. The applicable edition, test class and product coverage must be confirmed for the specific connector model. A general company certificate does not establish compliance of every cable connector with a particular electrical connection standard.

If your project requires a type-test report, material certificate, dimensional inspection report or other supporting document, please specify the exact requirement in your quotation inquiry. WISETREE can review the relevant documentation available for the selected product.

MOQ, Samples, Lead Time & Packaging

WISETREE supplies electrical cable connectors for distributors, industrial equipment manufacturers, electrical contractors and project procurement. Ordering requirements depend on whether the purchase involves a standard catalogue model or a specially manufactured connector.

For faster quotation, please provide the complete cable connector model number if known. If you are still selecting a connector, include the cable material, cross-section, preferred connection type and estimated purchasing quantity.

Frequently Asked Questions About Cable Connectors

Which cable connector should I choose for copper and aluminum conductors?

For a copper-to-copper cable joint, choose a copper cable connector designed for the conductor size and installation method. For an aluminum-to-aluminum joint, select a compatible aluminum connector. Where a copper conductor must be joined to an aluminum conductor, a suitable bimetallic cable connector or specifically approved transition connector is required. Confirm the material and cross-section on both sides before ordering.

What is the difference between compression cable connectors and mechanical cable connectors?

Compression cable connectors are installed using compatible crimping tools and dies. Mechanical cable connectors secure the conductors using bolts or shear-bolt connection systems. Compression models are commonly selected for a designated conductor size, while some mechanical designs accommodate a defined conductor range. The correct option depends on conductor compatibility, installation tooling and project specifications.

Can mechanical cable connectors join conductors of different sizes?

Some mechanical cable splice connectors are designed for unequal conductor sizes. WISETREE offers reducing configurations within its mechanical connector range. When selecting one, provide the material and cross-section of both conductors. The selected model must accommodate both conductor dimensions and meet the relevant installation requirements.

How do I select a cable connector for stranded or sector-shaped conductors?

Identify the conductor material, nominal cross-section, construction and shape before selecting a connector. A connector with a matching nominal cross-section is not automatically suitable for every conductor class. The model's conductor compatibility, insertion dimensions and installation instructions should be checked. Sector-shaped or flexible conductors may require additional consideration.

Are WISETREE cable connectors suitable for underground cable joints?

Suitable cable connectors may be used as conductor-joining components within an approved underground cable joint system. However, the connector itself does not provide the complete electrical insulation, sealing or environmental protection of the finished joint. The connector, joint enclosure and installation procedure must be compatible with the cable construction, voltage rating and project conditions.

Do WISETREE cable connectors comply with IEC 61238-1?

Compliance must be confirmed for the individual product model and the applicable test standard. If your project requires IEC 61238-1 or another specified electrical connection standard, provide the required edition and test requirements. WISETREE can review the relevant product information and available test documentation before order confirmation.

Can WISETREE manufacture custom electrical cable connectors from drawings?

Yes. WISETREE accepts custom cable connector inquiries and can evaluate dimensions, connector geometry, materials and other application-specific requirements against manufacturing feasibility. Send a drawing or reference sample, the conductor specification, required quantity and applicable technical requirements for evaluation and quotation.

What is the MOQ for copper, aluminum and mechanical cable connectors?

The minimum order quantity depends on the selected cable connector series, standard model availability and any special manufacturing or packaging requirements. Please provide the model numbers and estimated quantities for a quotation. Custom connector orders may have different minimum quantities from standard catalogue products.

Can I obtain cable connector samples and technical drawings before a bulk order?
