JJC Insulated Insulation-Piercing Grounding Clamp.High-Voltage Voltage-Testing Grounding Clamp with Tin-Plated Copper Teeth.No-Stripping Connecting Terminal.

JJC-001-2

Product Features

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.

Product Advantages

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.

Functional Features

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.
