What is an Insulation Piercing Connector? Professional Electrical Accessories Guide
What is an Insulation Piercing Connector? If you’ve ever delved into the intricacies of electrical systems, this question might have crossed your mind. Insulation piercing connectors (IPCs) are pivotal components in electrical installations, known for their ability to simplify and secure electrical connections. But what exactly are these connectors, and why are they so important in today’s electrical systems?
What is an Insulated Piercing Connector?
An insulated piercing connector is a type of electrical connector that is used to pierce the insulation of electrical wires to make a safe and reliable electrical connection. Insulation piercing connectors are typically used in power distribution and transmission systems as well as in telecommunications and automotive applications. They are designed to provide a strong and durable connection while maintaining the integrity of the insulation around the wire
How Insulation Piercing Connectors Work
The fundamental principle behind insulation piercing connectors is relatively straightforward. The connector is equipped with sharp metal teeth that pierce through the insulation of the wire, making direct contact with the conductor. This ensures a secure and reliable electrical connection without the need for stripping the insulation.
What are the components of an insulated drilled connector?
Insulation Piercing Connectors (IPCs) typically consist of multiple components that work in concert to create a reliable and secure electrical connection. The components of a WZJ Insulation Tap Connector include.
Shear head – Nut – Stainless steel washer – Upper body – Knife teeth – Watertight seal – Lower body – Stainless steel bolt – End cap.
These components work together to create a strong and reliable electrical connection without stripping the wire insulation, making IPCs especially useful in applications where the integrity of the insulation must be maintained.
Where are Insulation Piercing Connectors used?
Insulation Piercing Connectors (IPC) are used in a variety of electrical applications, including.
1. Power Distribution: IPCs are commonly used to connect and splice wires in power distribution systems. They are used to connect overhead power lines, underground cables, and transformers.

- 7. Cost-effective: By simplifying the installation process and minimizing the need for additional components, IPCs can reduce material and labor costs 8. Durable: Many IPCs are designed to withstand harsh environmental conditions, ensuring long-term reliability in outdoor and industrial environments.
How do I install an Insulation Piercing Connector?
Key Installation Steps.
- Insert the branch cable into the connector as shown.
- Insert the main cable. Cover the cable end cap
- Gradually tighten the nut until it shears off.
How do I test the performance of an IPC?
Type testing of Insulation Puncture Connectors (IPCs) is performed to verify the connector’s performance, safety, and compliance with relevant standards and specifications. These tests are typically performed on representative samples of IPCs and may include the following.
- Visual inspection and verification testing of dimensions and materials
- Permanent marking test
- Water intermediate voltage test
- Corrosion aging test (salt spray chamber test)
- Climatic aging test (UV radiation test)
- Main body mechanical damage test
- Branch cable pull-out test
- Connector bolt tightening test
- Shear head function test
- Low-temperature impact test
- Low-temperature assembly test
- Complete the electrical aging test (1000 cycles) and short-circuit test.
What is the NFC 33-020 standard for Insulation Piercing Connectors?
The NEC 33-020 standard is a French standard that defines the requirements for Insulation Piercing Connectors (IPC) used in low-voltage electrical and pneumatic equipment. The standard covers the design, materials, testing, and performance of IPCs, as well as the requirements for installation and use.
The NFC-33020 standard defines the characteristics of IPCs, including their size, shape, and depth of penetration, as well as their electrical and mechanical characteristics. It also specifies the tests that IPCs must undergo to ensure compliance with the standard, including resistance, mechanical strength, and environmental durability tests.
The standard also provides guidelines for the installation and use of IPCs, including recommended torque values for fasteners, minimum and maximum wire sizes that can be used with the connector, and the maximum current-carrying capacity of the connector.
What are the routine tests for Insulation Piercing Connectors?
Before an Insulation Piercing Connector (IPC) can be put into service, routine testing is required to ensure its quality, safety, and performance. These tests are usually performed during the manufacturing process and may include the following.
- Appearance inspection
- Permanent marking test
- Water intermediate electrical voltage test
- Cutting head function test – II
