    Product standard

    Compliant with GB/T 12706.4-2020 - Extruded insulation power cables and accessories rated for 1kV (Um=1.2kV) to 35kV (Um=40.5kV). Part 4: Test requirements for cable accessories rated 6kV (Um=7.2kV) to 35kV (Um=40.5kV).

     

    Product features

    • Exothermic welding process matching the cable core diameter, using high-quality welding materials to ensure the welded core maintains the same conductivity as the original cable.
    • Advanced fusion technology with premium materials enables perfect integration and cross-linking of the cable core, inner semiconductor, and main insulation layer by layer. This achieves complete cable restoration with intrinsic properties identical to the original cable body, thoroughly resolving issues of waterproofing, moisture resistance, and electric field concentration.
    • When connecting two medium-voltage cables with insufficient length at the joint, ZMJ can extend conductors within a certain length using exothermic welding, allowing power supply to be completed with just one ZMJ joint.
    • As the preferred cable connection technology, ZMJ demonstrates significantly better electrical reliability and stability compared to conventional cable accessory connections. With the widespread application of ZMJ's cable-body restoration technology, its high safety and reliability - featuring the same lifespan as the connected cable - eliminates repeated maintenance costs. It can effectively address special scenarios that traditional cable accessories cannot resolve.
