If the required aluminum cable connector cannot be identified from the product catalogue, please send the conductor details and application specifications to WISETREE for product matching.
Aluminum Cable Connector Specifications & Available Sizes
Correct selection of aluminum compression connectors starts with the conductor specifications. Aluminum cables with the same nominal cross-section may have different physical dimensions depending on conductor construction and shape. Therefore, the connector bore, conductor insertion requirements, and approved compression system must be checked before installation.
| Technical Specification | Selection Information | Why It Matters |
|---|---|---|
| Product Series | GL / GLB / GLI | Identifies the connector design and corresponding technical drawing. |
| Conductor Material | Aluminum or specified compatible aluminum alloy | Ensures correct conductor and connector material compatibility. |
| Conductor Cross-Section | Required cable size in mm² or equivalent AWG/kcmil | Determines the appropriate connector model. |
| Conductor Construction | Solid / Stranded / Other specified conductor class | Different conductor constructions may require different connector dimensions. |
| Conductor Shape | Round / Sector-shaped, where supported | Determines insertion compatibility and any required conductor preparation. |
| Overall Length | L (mm), according to the selected product drawing | Affects conductor insertion and available installation space. |
| Outer Diameter | D (mm), according to the selected model | Determines compatibility with the joint enclosure. |
| Inner Diameter | d (mm), according to the selected model | Must accommodate the approved conductor dimensions. |
| Connector Structure | Model-specific connection design | Determines the intended joint arrangement. |
| Surface Condition | Specified aluminum surface finish | Affects contact preparation and environmental considerations. |
| Jointing Compound | Where specified for the selected model | Supports the approved aluminum contact preparation procedure. |
| Installation Method | Approved compression or other model-specific method | Determines compatible installation tools and procedures. |
| Applicable Standard | Model-specific product or project specification | Supports engineering review and technical compliance assessment. |
Model Selection: For GL, GLB, and GLI aluminum cable connectors, request the dimensional drawing and conductor compatibility information corresponding to the required product. The exact available cross-section range, length, inner diameter, and outer diameter should be verified against the selected model rather than assumed to be identical across all three series.
For cable jointing projects involving different conductor sizes, specify the cross-section and material of both conductors. A reducing aluminum connector may require a different internal geometry from a standard equal-size aluminum cable splice connector.
How to Select Aluminum Compression Connectors
Choosing the correct aluminum compression connector involves more than matching a nominal cable size. The installer must consider conductor construction, aluminum material, connection geometry, and the approved compression system. The following guide helps customers prepare the information required for aluminum cable connector selection.
| Selection Step | Information to Check | Recommended Action |
|---|---|---|
| 1. Identify Conductor Material | Aluminum or aluminum alloy conductor | Confirm that the selected aluminum connector is approved for the conductor material. |
| 2. Confirm Cable Cross-Section | Nominal conductor size in mm² | Compare the cable specification with the connector's approved conductor range. |
| 3. Check Conductor Construction | Solid, stranded, compacted, or other conductor construction | Verify conductor class compatibility for the selected model. |
| 4. Identify Conductor Shape | Round or sector-shaped conductor | Check whether conductor preparation or reshaping is required under the approved installation procedure. |
| 5. Confirm Joint Configuration | Equal-size, unequal-size, or other specified conductor joint | Select a connector designed for both conductor ends. |
| 6. Check Mechanical Requirements | Non-tension or specified tension-bearing connection | Confirm whether the connector design and supporting tests meet the required mechanical duty. |
| 7. Select Crimping Equipment | Compression tool, die, and crimping profile | Use the approved installation system for the connector and conductor combination. |
| 8. Confirm Application Conditions | Installation environment, electrical requirements, and cable joint enclosure | Verify compatibility with the complete cable jointing system. |
Important: Two aluminum conductors with the same nominal cross-section may not have identical diameters or construction. For example, a solid aluminum conductor and a stranded aluminum conductor can require different connector specifications. Similarly, a sector-shaped conductor should not be inserted into a round-bore connector unless the model and approved installation method permit that arrangement.
For applications requiring mechanical rather than compression connections, explore our mechanical cable connectors to review alternative joining methods.
Aluminum Material, Jointing Compound & Oxidation Protection
Aluminum conductor connections require particular attention to surface condition, contact preparation, and oxidation protection. Aluminum naturally forms an oxide film when exposed to air. If the conductor and connector surfaces are not prepared according to the approved installation procedure, electrical contact performance may be affected.
For aluminum cable splice connectors, material specifications and contact protection arrangements should be reviewed together with the compression system. The following table outlines the key considerations when selecting aluminum cable joint connectors.
| Material / Construction Feature | Technical Consideration | Information Required for Procurement |
|---|---|---|
| Aluminum Material | The material grade and composition must meet the applicable connector specification. | Required aluminum grade, purity, or material standard. |
| Conductor Compatibility | The connector body must be suitable for the specified aluminum conductor. | Conductor material, size, and construction. |
| Oxide Layer Management | Aluminum contact surfaces require preparation according to the connector installation instructions. | Specified contact preparation and installation method. |
| Jointing Compound | Some aluminum compression connector designs use a suitable jointing compound to help maintain the prepared contact interface. | Whether the selected model is prefilled and the required compound specification. |
| Protective Sealing | Certain connector designs may use protective caps or packaging to preserve the condition of the contact surface or jointing compound. | Required packaging and storage conditions. |
| Center Stop | A center stop, where incorporated, can help position conductors during installation. | Product drawing and center-stop requirements. |
| Conductor Entry Design | Suitable entry geometry helps accommodate the approved conductor construction. | Required bore dimensions and conductor insertion details. |
When purchasing aluminum compression connectors with prefilled jointing compound, confirm the compound specification, product storage requirements, and installation procedure. Prefilled compound should not be assumed for all GL, GLB, and GLI aluminum connector models.
WISETREE can review customer requirements for aluminum material, connector dimensions, surface preparation, and special contact protection arrangements during product selection or custom manufacturing evaluation.
Aluminum Connector Crimping & Installation Requirements
Proper installation is essential for aluminum crimp connectors and aluminum compression joints. The selected connector must be used with a compatible crimping tool, die, and conductor preparation procedure. Crimping profiles, locations, and the number of compressions depend on the product model and approved installation system.
| Installation Item | Recommended Check | Purpose |
|---|---|---|
| Cable Preparation | Strip the insulation to the length specified in the installation instructions. | Allows correct conductor insertion without damaging the strands. |
| Surface Preparation | Follow the approved aluminum conductor contact preparation procedure. | Helps establish the intended electrical contact interface. |
| Connector Inspection | Inspect the connector body, bore, and any protective sealing before installation. | Identifies visible damage or unsuitable product condition. |
