Simple and Fast Cold Pour Application

The cold pour cast resin system enables quick and secure installation, with a curing time of only 30-45 minutes. Each kit includes all necessary components-cast resin, mixing containers, casting mould, and adhesives-to streamline on-site cable jointing for manufacturers, service providers, and wholesalers alike.

FAQ's of Cast Resin Voltage Joint:

Q: How is the cast resin voltage joint applied and what is the installation process?

A: The cast resin voltage joint utilizes a cold pour system. The process involves preparing the cable ends, assembling the supplied casting mould around the joint area, mixing the resin, and pouring it into the mould. The resin cures in 30-45 minutes, forming a seamless, protective barrier with a smooth finish and strong adhesion to cable sheaths.

Q: What types of cables are compatible with this voltage joint?

A: This joint is compatible with both single and multi-core XLPE or PVC cables within the 70 to 400 sq.mm range, making it ideal for a wide variety of high-voltage electrical installations and cable sizes up to 11 kV supply voltage.

Q: When should I use this cast resin voltage joint?

A: Use this joint when you require robust insulation and protection for high-voltage cable connections, especially in environments needing submersibility or exposure to moisture, chemicals, or UV. It's perfect for both indoor and outdoor electrical and wiring projects demanding high reliability.

Q: Where can this cast resin joint be installed?

A: This product can be installed in both above-ground and underground locations, including wet, damp, and fully submersible environments, thanks to its IP68 rating and permanent water ingress protection. It's suitable for utility, industrial, and infrastructure projects.

Q: What are the primary benefits of using this voltage joint?

A: Key benefits include superior insulation and flame retardancy, high mechanical protection, excellent adhesion to cable sheath, permanent water resistance, and a fast, cold-cure installation process. These features combine to provide long-term reliability and safety for high-voltage electrical systems.

Q: How long is the shelf life and does storage condition affect performance?

A: The shelf life of the unopened cast resin voltage joint pack is 12 months. Store it in a cool, dry place to maintain resin quality and ensure optimal performance upon use.

Q: Is the cast resin joint suitable for high-current applications?

A: Yes, the joint is rated for currents up to 630 A and operates efficiently at frequencies of 50 Hz, making it suitable for demanding power transmission and distribution systems.
