SİP-2, SİP-2A
Areal insulated wires of up to 0,6/1 kV voltage.
Test voltage of wires is 4 kV a.c.at frequency of 50 Hs during 1 hour. The wires have an ability to the bending at the temperature of minus 40°C.
The processes of wires laying and assembling are provided at the ambient temperature not below than minus 20°C.
Permissible temperature of heating of the conductors at normal mode is: for the SİP-1, SİP-IA wires 70°C;
for the SİP-2, SİP-2A wires 90°C.
– Permissible short-circuit temperature: <250°C.
SİP-1, SİP-1 A are bundle assembled aerial wires with aluminium current-conducting conductors, in light-stabilized polyethylene insulation, with zero messenger. SİP-1, SİP-1 A is bundle assembled aerial wires with aluminium current-conducting conductors, light-stabilized cross-linked polyethylene insulated, with zero messenger. (The letter ‘A’ corresponds to insulated messenger). The wires are used for air electrical networks and branches to entering in dwellings, economic buildings in regions of moderate and cool climate.
