Cable Jointing

Cable Jointing

 

Flame-Retardant Type: Designed for T-junctions of flame-retardant cables, injection-moulded from high-quality reinforced, flame-retardant, and high-temperature-resistant engineering plastic insulation.

Fire-Resistant Type: Designed for T-junctions of fire-resistant (including mineral-insulated fire-resistant) cables, fabricated from fired mineral insulating refractory materials, capable of withstanding temperatures in excess of 1500°C.

Sealing and Waterproofing System

 

The sealing system helps protect the cable branch connection from moisture, dust and external environmental conditions.
The sealing components are designed to work with the integrated branch joint structure, providing insulation and sealing around the cable connection area.
The sealing system is suitable for low-voltage cable branching applications in indoor and outdoor environments. The actual protection level depends on the selected product configuration and installation conditions.
