Introduction to Insulation Piercing Connector (IPC)

An Insulation Piercing Connector (IPC) is an advanced electrical connector designed to create a secure, reliable, and safe connection between two conductors without the need to strip their insulation. It is commonly used in low-voltage distribution networks, overhead lines, and solar photovoltaic (PV) systems.

Benefits of Insulation Piercing Connector

1. No Insulation Stripping Required
   The IPC eliminates the need to strip insulation from the cable, saving time and reducing the risk of conductor damage or improper contact.
2. Fast and Easy Installation
   Installation is simple and requires no special tools—just a standard wrench. The integrated shear-head bolt ensures the correct tightening torque automatically.
3. Waterproof and Weather-Resistant
   IPCs are sealed with rubber gaskets and designed to withstand outdoor conditions. Most are rated IPX7 or IPX8, offering excellent water and UV resistance.
4. Safe and Reliable Connection
   The connector's piercing teeth ensure a consistent and durable electrical contact, reducing resistance and preventing overheating.
5. Multi-Material Compatibility
   Suitable for both copper and aluminum conductors, which makes IPCs versatile across various applications.
6. Maintenance-Free Operation
   Once installed, IPCs require little to no maintenance, reducing long-term operation costs.
7. Compact and Space-Saving
   IPCs are compact in design, ideal for installations with limited space such as solar PV junctions or street lighting poles.

How to Use an Insulation Piercing Connector

1. Position the Cables
   Place the main conductor and the branch conductor into the connector's respective slots without removing their insulation.
2. Tighten the Torque Bolt
   Use a wrench to tighten the shear-head bolt. As the bolt is tightened, the metal teeth inside the IPC pierce the insulation and make contact with the conductor.
3. Achieve Proper Contact
   Continue tightening until the shear head snaps off. This indicates that the correct torque has been reached and the connection is secure.
4. Seal the Connector
   Ensure that the rubber sealing elements are properly in place to prevent water ingress. Some models include caps or gel seals for additional protection.
5. Check the Connection
   Perform a quick visual and physical inspection to ensure the connector is firmly in place and properly sealed.

Typical Applications:

• Solar PV systems
• Overhead and underground low-voltage power distribution
• Street lighting and outdoor electrical installations
• Temporary or permanent tap connections
