1. Piercing Structure
No stripping of insulated conductors is required during installation, enabling simple operation.
2. Torque Nut
The constant piercing pressure ensures good electrical contact without damaging the conductor.
3. Self-Sealing Structure
Features moisture-proof, waterproof, and corrosion-resistant properties, extending the service life of insulated conductors and clamps.
4. Contact Blade
Equipped with 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, meeting relevant standards.
The insulating housing is resistant to light and environmental aging, with a dielectric strength >12kV.
6. Arc Surface Design
Suitable for connecting same/different diameter conductors, with a connection range of 0.75mm² - 400mm².
1. Simple and Reliable Installation
Cable branching can be done without stripping the cable insulation, and the joints are fully insulated.
No need to cut the main cable, allowing branching at any position on the cable, and it can be installed live energized.
2. Safe Operation
The joints are resistant to twisting, vibration, water, fire, and electrochemical corrosion aging, requiring no maintenance.
3. Cost Saving
Small installation space reduces costs for cable trays and civil engineering.
In construction applications, no terminal boxes or distribution boxes are needed, and no cable return lines are required, saving cable investment.
1. Suitable for Multiple Types of Connections
Mainly applicable to the jointing, branching, and grounding protection of overhead insulated conductors, with applicable voltage classes including 20kV, 10kV, and 1kV and below.
2. Realization of Electrical Connection
Without damaging the conductor, the piercing blade penetrates the conductor's insulation layer to achieve reliable electrical connection and mechanical fixation between conductors.
