Category:

The Thermoplastic Insulation Piercing Connector is designed for reliable and durable service connections in low-voltage (LV) electrical networks. Manufactured with UV-resistant, waterproof thermoplastic, it ensures long-term stability under harsh outdoor conditions. This Thermoplastic Insulation Piercing Connector enables quick, secure, and maintenance-free connections between insulated aluminium or copper conductors without the need to strip cable insulation.

Standard Compliance: NFC 33-020, ANSI C119.5, EN 50483-4

Construction & Materials

  • Contact Blades: Tin-plated copper or aluminium alloy (90.2-105HB)

  • Body: Reinforced fiberglass thermoplastic for superior strength

  • Sealing: Waterproof elastomeric caps for reliable insulation protection

Performance & Reliability

The connector is tested according to EN 50483-4, NFC 33-020, and ANSI C119.5 standards to ensure mechanical, electrical, and environmental endurance:

  • Withstands 6 kV voltage in a 30 cm water bath

  • Stable contact resistance after overload and load cycling

  • Proven corrosion resistance under salt fog and SO₂ chamber tests

  • Withstands UV, humidity, and temperature cycling without degradation

Installation Guide

Use a Dielectric Torque Wrench to install the connector. The shear-head nut ensures the correct torque is automatically applied for optimal contact and sealing. The design enables quick installation without cable stripping, minimizing the risk of conductor damage and ensuring long-lasting performance.

  • Precision Torque Control: Features a shear-bolt head that automatically shears off at the correct torque, guaranteeing consistent, secure, and maintenance-free connections.

  • Enhanced Safety: Fully insulated, waterproof body with nonconductive sealing prevents accidental contact with live components and ensures long-term electrical safety.

  • Durable, Corrosion-Resistant Construction: Made from high-quality copper or aluminum with bimetallic tin-plated teeth for compatibility with both copper and aluminum conductors.

  • UV-Resistant and Flame-Retardant: Engineered to withstand harsh environmental conditions, providing excellent performance in outdoor and high-temperature applications.

  • Low Maintenance and Cost-Effective: Designed for extended service life with minimal upkeep, reducing installation time, operational costs, and system downtime.

FAQs – Telexc Insulation Piercing Connectors

1. How do I choose the right insulation piercing connector?
Select a connector suitable for your cable size and application. Telexc IPCs feature easy installation—no need to strip or cut the main cable insulation. They can be installed at any point along the line using a standard wrench, even on live conductors, ensuring a simple and reliable setup.

2. Are Telexc Insulation Piercing Connectors safe to use?
Yes. Telexc connectors are resistant to mechanical stress, vibration, moisture, corrosion, and aging. They have been proven in long-term field use for over 30 years with minimal maintenance requirements.

3. What are the economic advantages of using Telexc IPCs?
Their compact design minimizes installation space and eliminates the need for terminal or junction boxes, reducing both material and labor costs.

4. What types of cables are compatible with Telexc IPCs?
They are designed for low-voltage aerial bundled conductors (LV-ABC) and service cables, making them ideal for connections between utility lines and customer premises.

5. What tools are needed for installation?
Only a standard wrench with the correct hex socket size is required—no special tools are necessary.

6. How can I ensure the correct tightening torque during installation?
Each Telexc connector features a shear-head bolt that breaks off automatically when the optimal torque is reached, guaranteeing proper contact pressure and electrical reliability.

7. Do I need to strip the cable insulation before installation?
No. The built-in piercing blades automatically penetrate the cable insulation to create a secure electrical connection.

8. Is there any risk of electric shock from exposed metal parts?
No. Telexc IPCs are fully insulated, and all conductive parts are safely enclosed to prevent accidental contact during and after installation.
