SIP-3 SIPn-3 AAsXS AAsXSn Wires for Overhead Power Lines

SIP-3 SIPn-3 AAsXS AAsXSn Description

SIP-3 (ААsXS) are self-supporting insulated wires with a conductor made of aluminum alloy and insulation made of light-stabilized cross-linked polyethylene.
SIPn-3 (ААsXSn) are self-supporting protected wires with a conductor made of aluminum alloy and insulation made of light-stabilized cross-linked polyethylene, which does not spread combustion.
They are designed for overhead power transmission lines with a rated voltage of 20 kV (for networks with a voltage of 10, 15 and 20) kV and 35 kV (for networks with a voltage of 35 kV) with a rated frequency of 50 Hz.

INTERPRETATION OF WIRES SIP-3, SIPN-3, ААSXS, ААSXSN

S – self-supporting;

n – does not support combustion.

SIP-3 SIPn-3 AAsXS AAsXSn Detailed

SIP-3 (ААsXS) is a self-supporting protected insulated wire with a conductor made of aluminum alloy and protective insulation made of cross-linked polyethylene.
The main difference between this wire and other types of self-supporting wires is the voltage for which it is designed. So, if the wires SIP-1, SIP-2, SIP-4, SIP-5 are intended for power and lighting networks for an alternating voltage of 0.6 / 1.0 kV, then SIP-3 is a high-voltage wire used in networks with a rated voltage of 20 kV and 35 kV with a rated frequency of 50 Hz.

SIP-3 SIPn-3 AAsXS AAsXSn Applicability scope

SIP-3 and ААsXS are designed for overhead power transmission lines in areas with temperate, cold and tropical climates. They are used for laying highways of overhead power transmission lines with a voltage of 20-35 kV and linear branches thereof.
SIP-3 began to be used for the installation of power lines instead of traditional uninsulated wires A and AS and immediately provided greater safety for maintenance personnel, lower operating costs and reduced line breakdown rates by minimizing damage to wires and the absence of their entanglement with each other and with tree branches. Due to insulation, even if you accidentally touch the wire, the risk of electric shock is minimal, and in the event of an emergency falling trees or twisting wires, the uninterrupted supply of electricity does not stop.
SIP-3, ААsXS wires are safe to use and do not emit harmful substances into the air even in case of significant heating.
SIPn-3 and ААsXSn are non-flammable types of wire that do not spread combustion and do not form burning particles.
