Full details
The WISKA WSJA5 STRAIGHT Resin Cable Joint is designed for electricians and installers needing a reliable solution for jointing 0.6-1kV single and multicore cables up to four-cores. Its key benefit is providing excellent electrical insulation and mechanical strength for overhead, underground, and underwater installations, including public lightning systems. A potential caveat to consider is the 3-year shelf life of the resin, requiring attention to stock rotation.

Troubleshooting
Resin does not cure properly
Ensure the two-component resin was mixed in the correct ratio and thoroughly combined. Verify that the ambient temperature is within the recommended range for curing. Check the shelf life of the resin; expired resin may not cure effectively.
Air bubbles present in the cured resin
Ensure the resin was injected slowly and steadily to minimize air entrapment. Tap the half-shells gently after injection to help trapped air rise to the surface. Ensure all connections and cable entries are properly sealed before injection.
Joint appears loose or connectors are not secure
Verify that the correct size insulated crimp connectors were used and that they were crimped securely onto the cable cores. Ensure the cable diameter falls within the specified 33-55mm range for this joint.

Setup, Compatibility & Care
Setup:
- Prepare the cable ends according to standard procedures, ensuring they are clean and stripped to the correct length.
- Assemble the modular phase separator and install the insulated crimp connectors onto the cable cores.
- Insert the prepared cable ends into the transparent half-shells.
- Mix the two-component resin thoroughly as per the manufacturer's instructions.
- Using the direct injection casting system, carefully fill the half-shells with the resin, ensuring complete coverage of the joint and connectors.
- Allow the resin to cure fully according to the specified time, typically indicated by hardening.
- Once cured, remove the transparent half-shells to reveal the completed resin-potted joint.
Compatibility:
- Suitable for 0.6-1kV single and multicore cables.
- Specifically designed for 4-core cables within the 33-55mm diameter range.
Care:
- Store the kit in a cool, dry place. Pay attention to the 3-year shelf life of the resin components.
- Ensure all tools and surfaces are clean before starting the installation to prevent contamination of the resin.
- Follow safety guidelines when working with electrical cables and resin compounds.
