HELTC 1KV Insulation Piercing Connector – No-Strip Cable Branch Clamp
Make cable branching fast, safe, and tool-efficient with the HELTC Insulation Piercing Connector. Rated at 1KV and engineered for both high and low voltage applications, this clamp lets you tap into a main cable line without ever stripping the insulation. Whether you're wiring street lighting, industrial power distribution, bridge illumination, or garden electrical systems, this connector delivers a secure, sealed, professional-grade connection every time.
Made in Mainland China.
Key Features
- No Peeling Required: Branch off from main cables without stripping insulation or interrupting the main conductor — saving time and reducing installation risk.
- Flame-Retardant Insulated Shell: The rugged PVC outer shell resists damage, erosion, aging, moisture, and dust — built tough for outdoor and industrial environments including road lighting, bridges, and garden power projects.
- Sealed Internal Structure: Filled with insulating thermal oil, the clamp forms a fully sealed interior upon installation, maximizing insulation integrity and conductivity performance.
- Tin-Plated Pure Copper Piercing Plate: The copper piercing contact is tin-plated for outstanding conductivity, oxidation resistance, and compatibility with both copper and aluminum conductors.
- Live-Circuit Capable: Can be installed on energized (live) circuits, eliminating the need for power outages during installation — ideal for overhead service taps and street lighting connections.
- Prevents Hotspots & Loose Connections: Ensures a premium, stable electrical contact that guards against hotspots, loose connections, or wire damage over time.

Frequently Asked Questions
Q: What does "no peeling required" mean for an insulation piercing connector?
A: It means you do not need to strip or remove the insulation from the main cable before making your branch connection. The piercing teeth on the clamp's copper contact penetrate the cable insulation as the connector is tightened, making direct electrical contact with the conductor inside — saving time and reducing the risk of accidental wire damage.
Q: Can the HELTC insulation piercing connector be used on live (energized) circuits?
A: Yes. These connectors are designed to be installed on live circuits, which means you can branch a cable without cutting power to the main line. However, always follow local electrical safety codes and use appropriate personal protective equipment (PPE) when working with energized conductors.
Q: Is this connector compatible with both copper and aluminum wires?
A: Yes. The tin-plated pure copper piercing plate is compatible with both copper and aluminum conductors, making the HELTC connector versatile for a wide range of residential, commercial, and industrial wiring applications.
Q: Which model should I choose for my cable size?
A: Choose based on your main line and branch line cross-sectional area (mm²): JJC-1 for main lines 1.5–35 mm² / branch 1.5–10 mm²; JJC-2 for main 16–95 mm² / branch 1.5–10 mm²; JJC-3 for main 16–95 mm² / branch 4–50 mm²; JJC-4 for main 50–150 mm² / branch 6–50 mm². When in doubt, always size up to ensure a proper and safe connection.
Q: Is this connector suitable for outdoor use?
A: Absolutely. The flame-retardant PVC shell is moisture-resistant and dustproof, making it well-suited for outdoor installations such as street lighting, garden illumination, bridge lighting, and overhead power distribution systems.
