What cables are used with insulation piercing connectors?

Insulation piercing connectors (IPC) are mainly used to make a connection between protected low voltage overhead lines.

There are The 3 main types of LV-ABC are used with insulation piercing conenctors:

•  Self-supporting LV-ABC lines

The self-supporting system is composed of 4 insulated aluminium conductors. Mechanical strength and nominal cross section of all 4 conductors are identical. The system can consist of additional 1 or 2 insulated aluminium conductors with cross sections of 16 mm2 or 25 mm2as pilot wire or for street lighting.

When straining the line, all 4 conductors are equally loaded. The service lines of all 3 LV-ABC systems are usually also of the self-supporting type, composed of 2 to 4 factory bundled insulated aluminium conductors with cross sections of 16 mm2, 25 mm2 or 35 mm2.

• LV-ABC lines with insulated neutral messenger

LV-ABC line with insulated neutral messenger wire, also referred to as “French System”, is composed of 3 insulated aluminium phase conductors and 1 neutral messenger of aluminium alloy (mostly Aldrey) also with insulation. The system can consist of additional 1 or 2 insulated aluminium conductors with cross sections of 16 mm2 or 25 mm2 as pilot wire or for street lighting.
Mechanical strength and nominal cross section of the 3 phase conductors are identical. The neutral conductor is at the same time the suspension unit having a higher mechanical strength. When straining the line, only the neutral conductor, as suspension unit, is loaded. 

• LV-ABC lines with bare neutral messenger

LV-ABC line with bare neutral messenger wire, also referred to as “Finnish System”, is composed of 3 insulated aluminium phase conductors and 1 neutral messenger of aluminium alloy without insulation. The system can consist of additional 1 or 2 insulated aluminium conductors with cross sections of 16 mm2 or 25 mm2 as pilot wire or for street lighting.

Mechanical strength and nominal cross section of the 3 phase conductors are identical. The neutral conductor is at the same time the suspension unit having a higher mechanical strength. When straining the line, only the neutral conductor, as suspension unit, is loaded.
