1. Piercing Structure
No stripping of insulated conductors is required during installation, enabling simple and convenient operation.
2. Torque Nut
The constant piercing pressure ensures good electrical connection without damaging the conductor.
3. Self-Sealing Structure
With moisture-proof, waterproof, and corrosion-resistant properties, it extends the service life of insulated conductors and clamps.
4. Contact Blade
Equipped with specially designed contact blades, suitable for copper-aluminum butt connection and copper-aluminum transition.
5. Excellent Electrical Performance
Low electrical contact resistance, less than 1.1 times the resistance of an equal-length branch conductor, complying with the DL/T765.1-2001 standard.
Meets the requirements of relevant technical specifications.
6. Insulated Housing
The special insulated housing is resistant to light and environmental aging, with a dielectric strength >12kV.
7. Arc Surface Design
Suitable for connecting same/different diameter conductors, with a wide connection range of 0.75mm²–400mm².
1. Easy Installation
No need to strip the insulation of the cable for making cable branches. The joints are fully insulated, allowing live installation. Branches can be made at any position of the cable, only requiring a socket wrench.
2. Safe to Use
The joints are resistant to twisting, vibration, water, fire, and electrochemical corrosion aging, requiring no maintenance.
3. Cost-saving
It requires small installation space, saving costs for cable trays and civil engineering. In construction applications, terminal boxes, distribution boxes, and cable return lines are unnecessary, reducing cable investment.
JJC insulation piercing cable clamps are suitable for different voltage levels, such as 1KV, 10KV, 20KV, 35KV, etc. They are mainly used in insulation cable branching of building power distribution systems, low-voltage overhead insulated cable connections, low-voltage insulated service entrance cable branching, street lighting power distribution systems, etc., and can realize functions such as branching, jointing and grounding protection of insulated cables.
