FAQs (Telexc TTD-Series Insulation Piercing Connector)

1. What types of conductors are compatible with TTD-Series IPC?
The TTD-Series connectors are compatible with insulated aluminum and copper conductors commonly used in LV ABC (Aerial Bundled Cable) systems. Bimetallic tin-plated teeth ensure reliable contact with both metals.

2. Do I need to strip the cable insulation before installation?
No. The insulation piercing design eliminates the need to strip insulation from either the main or tap conductors, allowing faster and safer connections.

3. Can TTD-Series connectors be installed on live lines?
Yes. The connectors feature fully insulated, nonconductive bodies and end caps, enabling safe live-line installation when using proper tools and safety procedures.

TTD-Series connectors are rated for low-voltage systems, typically 400/600 V (0.4–0.6 kV), with tested voltage withstand up to 6 kV under water for 1 minute.

5. How does the shear-bolt system work?
The shear-bolt automatically breaks when the correct torque is applied, ensuring consistent contact pressure and preventing over-tightening that could damage the conductor.

6. Are TTD-Series connectors waterproof and UV-resistant?
Yes. The connectors are fully waterproof, UV-stable, and made from flame-retardant thermoplastic with fiberglass reinforcement for long-term outdoor performance.

7. What maintenance is required after installation?
TTD-Series IPCs are designed for minimal maintenance. Once installed correctly, they provide durable, corrosion-resistant, and secure connections over the long term.

8. Can these connectors be used in both residential and commercial applications?
