Which Cables Are Suitable for Insulation Piercing Connectors: 3 Main Types
Insulation Piercing Connectors (IPCs) are revolutionizing the way we think about electrical connections. They offer a quick, reliable, and safe method of connecting insulated cables without the need for stripping the insulation. However not all cables are created equal, and choosing the right type for IPCs is crucial for ensuring optimal performance and longevity. In this article, we’ll delve into which cables are best suited for insulation piercing connectors and why they are the top choices.
What are Insulation Piercing Connectors?
Insulation Piercing Connectors are devices designed to connect electrical cables without the need for stripping the insulation. They have sharp teeth that pierce through the insulation and make contact with the conductor, providing a secure electrical connection.
How do IPCs work?
IPCs work by using a compression mechanism that forces the connector’s teeth through the cable’s insulation into the conductor. This creates a reliable electrical connection while maintaining the insulation integrity around the rest of the cable.
Key Features of Suitable Cables
Conductor Material
The conductor material is vital for compatibility with IPCs. Copper and aluminum are the most commonly used materials due to their excellent electrical conductivity and mechanical properties.
Insulation Type
The insulation type affects the performance and safety of the connection. Common insulation materials include cross-linked polyethylene (XLPE), polyvinyl chloride (PVC), and ethylene propylene rubber (EPR).
Cable Size and Compatibility
Choosing the right cable size is essential for ensuring a secure connection. IPCs are designed to accommodate a range of cable sizes, so it’s important to select cables that fit within the specified size range.
Suitable Cable Types for IPCs
Insulation Piercing Connectors (IPC) are mainly used to connect protected low-voltage overhead lines.
There are 3 main types of LV-ABCs used in conjunction with Insulation Puncture Connectors.
1. Low Voltage Cables
XLPE Insulated Cables
XLPE (Cross-Linked Polyethylene) insulated cables are popular for their high thermal resistance and excellent electrical properties, making them ideal for IPCs in low-voltage applications.
PVC Insulated Cables
PVC (Polyvinyl Chloride) insulated cables are widely used due to their durability and cost-effectiveness. They provide good insulation and are suitable for a variety of IPC applications.
2. Medium Voltage Cables
EPR Insulated Cables
EPR (Ethylene Propylene Rubber) insulated cables are known for their flexibility and high insulation resistance. They are suitable for medium voltage applications where IPCs are used.
3. High Flexibility Cables
Silicone Rubber Insulated Cables
Silicone rubber insulated cables offer high flexibility and thermal stability, making them ideal for applications where cables need to be bent or twisted frequently, and are compatible with IPCs.
3 Main Types of LV Cables Suitable for Insulation Piercing Connectors
Self-supporting LV-ABC lines
The self-supporting system consists of 4 insulated aluminum conductors. All 4 conductors have the same mechanical strength and nominal cross-sectional area. The system can be made up of 1 or 2 additional insulated aluminum conductors with a cross-sectional area of 16 mm2 or 25 mm2 for use as wires or for street lighting.
All 4 conductors are subjected to the same load when the line is tensioned. The service line of all 3 LV-ABC systems is also normally self-supporting and consists of 2 to 4 factory-bundled insulated aluminum conductors with a cross-sectional area of 16 mm2, 25 mm2, 35 mm2.
LV-ABC line with insulated neutral conductor
The LV-ABC line with insulated neutral, also known as the “French system”, consists of 3 insulated aluminum phase conductors and an aluminum neutral (mainly Audrey), also insulated. The system can consist of one or two additional insulated aluminum conductors with a cross-sectional area of 16 mm2 or 25 mm2 for control lines or street lighting. the three-phase conductors have the same mechanical strength and nominal cross-sectional area. The neutral wire is also a suspension device with higher mechanical strength. When tensioning the line, only the neutral wire, which is the suspension, is subjected to the load.
LV-ABC line with exposed neutral messenger
The LV-ABC line with bare neutral, also known as the “Finnish system”, consists of 3 insulated aluminum phase conductors and an uninsulated aluminum neutral. The system can consist of one or two additional insulated aluminum conductors with a cross-sectional area of 16 mm2 or 25 mm2 for use as conductors or street lighting. The phase conductors have the same mechanical strength and nominal carrying surface. Neutral conductors are at the same time suspension units with higher mechanical strength. When tensioning the line, only the neutral conductor, as the suspension unit, is subjected to the load.
