Cable Sip
Cable CIP – Benefits 1. Reducing the voltage drop due to significantly lower reactance (an average of 0.1 ohm / km instead of 0.35 ohms / km), which increases the load in kW for the same line and same voltage dip or improves the quality of the transferred energy at the same load. 2.Umenshenie power line installation costs associated with cutting down a more narrow clearing in the forest areas, the possibility of using shorter poles (recommended distance to the ground for insulated wire is 4 m for bare – 8 pm) 3.Uproschenie process laying new lines, simple retrofitting of existing lines with bare wires on the line with self-supporting insulated wires. 4.Vozmozhnost installing additional parallel to the existing CIP to double the capacity of the network (which is unacceptable when using bare wires). 5.Vozmozhnost joint Laying on the same supports both SIP and high-voltage overhead lines 6-20 kV with bare wires or protected. 6.Vozmozhnost simultaneous mounting on the same phone line supports (0.5 m lower than wire CIP). 7.Rezkoe reduction (80%) of operating costs due to high reliability and trouble-free energy consumers, and there was no need to clear firebreaks in the process of operating the line replacement of damaged insulators. 8.Prostota assembly, the ability to connect new subscribers under stress, without shutting down the rest of the energy supply and as a consequence of shortening the repair and installation.
Reduction the risk of fires in wooded or brushy area in the fall to the ground wire. 9.Umenshenie safe distances from buildings and civil engineering (electrical, telephone, air-lines) that provides greater flexibility when installing. 10.Vysokaya security service – no risk of defeat at the touch of the phase conductors under tension; 11.Otsutstvie or slight sleet and fouling isolated surface wet snow wires. This is explained by the fact that PE is not a polar dielectric, and it does not produce any electrical or chemical bonds with them in contact with the substance. It is for this reason Wet snow is easily flows from the round surface of isolated PE wires. In the wire type A and AS wet snow can be retained in the grooves between the wires, being the root cause of fouling. 12.Povyshennaya safety zones heavy icing, glaze, reduction of wind loads on the supports; 13.Bespereboynoe electricity in case of failure of CIP to the supports.
