SIP-4 Self-supporting Insulated Overhead ABC Aerial Power Wire Cable
SIP Cable Application
Power supply of end consumers (facility, living quarters), as well as lighting of various areas can be carried out using self-supporting insulated wires. One of the types of SIP, which is used for these purposes, is the SIP-4 wire in question. A feature of this type is the absence of a carrier zero core. This type of cable is used to equip branches from overhead power lines to transformer units. They can be used for the construction of lighting power grids or for laying on the walls of construction sites. The main technical properties of insulated electric wires provide the ability to operate in alternating current networks at 1000 Volts and 50 Hz.
SIP-4 Cable Construction
SIP-4 is made of compacted aluminum wire with a twist pitch of up to 45 cm. The wire, as a rule, has 2-3-4 conductive stranded conductors of the same nominal cross-section, and also, in some cases (as mentioned above), an additional smaller conductor is added section.
The wire is mainly produced with a cross section of 16-120 mm2. In this case, if the nominal cross-section does not exceed 25 mm2, a right-sided twisting is used, for large sizes - a left-sided one.
All cores of the wire are insulated with thermoplastic light-stabilized black cross-linked polyethylene, resistant to ultraviolet radiation throughout the entire service life.
This insulation provides the cable with resistance to all types of atmospheric precipitation, as well as to significant and sharp changes in ambient temperature.
