😳Internal wiring for a house with a self-supporting insulated wire (SIP) system. Why?
SIP stands for self-supporting insulated wire.
This type of wire is used for laying main overhead power lines (OVL) and their branches. For example, from an overhead power line to a country house or cottage.
SIP is used in AC networks with voltages from 0.6 to 35 kV at temperatures from -60 to +50°C. The service life of the wires is at least 40 years.
These wires cannot be laid underground, as their insulation is not suitable for such operating conditions.
