Insulation piercing connectors (IPCs) are specialized electrical connectors designed to connect conductors without removing the insulation. This feature significantly speeds up installation and reduces labor costs. They achieve this by using specially designed blades that pierce the insulation, making contact with the conductor underneath. This type of connector is particularly useful in overhead power lines and other applications where removing insulation is impractical or time-consuming. Several Chinese manufacturers, such as Zhejiang Sentuo Electric Co., Ltd. (www.sentuoelectric.com), are prominent suppliers in this market.

Technical Features of Insulation Piercing Connectors

The performance of an IPC is determined by several key technical features. These features vary depending on the specific design and intended application. Understanding these differences is essential for selecting the appropriate connector for a given task. The following table compares some critical technical specifications:

Feature Specification 1 Specification 2 Specification 3
Voltage Rating (kV) 1 6 10
Current Rating (A) 100 150 200
Conductor Size (mm²) 16-95 50-150 10-240
Material Copper Alloy Aluminum Alloy Tinned Copper
Insulation Material PVC XLPE PE
Water Resistance Yes Yes Yes
UV Resistance Yes Yes Yes

Different Types of Insulation Piercing Connectors

Several types of IPCs are available, each designed for specific applications and cable types. The choice depends on factors like voltage rating, current carrying capacity, cable size, and environmental conditions. Here’s a comparison of some common types:
