SIP-3/O – self-supporting insulated wire with integrated fiber-optic cable.
SIP-3/O is designed for transmission and distribution of electric energy in the air, power and lighting networks on 10 kV - 35 kV and for communications via optical cable.
Cable is made in the form of "8" and consists of current-carrying conductor and optical core. The current-carrying conductor is made of wires aluminum alloy and sealed.
Central strength member is made of fiber reinforced plastic rod (FRP). Polymers tubes are SZ-stranded around central strength member. Cable contains 2-144 optical fibers for information transmission.
The outer jacket is made of UV stable polyethylene which is formed around current-carrying conductor and optical core with connecting part.
