Vasyurinskoy Dinskoy

First influ with these wires in Russia was built in the Krasnodar Territory in 1994 in the village Vasyurinskoy Dinskoy area. Its length was 3.5 km. Manufacture of wires and brands SAPTA SAPssh was soon discontinued due to the release of the TU-268 16.K71-98, which were developed based on the international harmonized standard HD626S1 VNIIKP with OAO Sevkabel 'and with the participation of the department of electrical networks RAO UES of Russia', 'Lenenergo' Institute 'Zapadselenergoproekt'. So, at present, there are three of SIPs, which have advantages and disadvantages. Consider a data system for the example table: Characteristics of CIP System CIP brand in Russia AMKA ('Finnish' system) around the bare ('bare') carrying neutral conductor stranded insulated phase conductors. Cable carrier is made of aluminum alloy high strength.

STS-2 Torsada ('French' system) around insulated carrying neutral conductor stranded insulated phase conductors. Cable carrier is made of aluminum alloy high strength. STS-1 EX Four Core ALUS ('Swedish' system) Suspension wire is missing. All conductors of aluminum. All conductors of equal cross-section. STS-4 Thus, we can distinguish 'Finnish' system with the bare carrier housing and the 'French' system with isolated neutral.

Due to the fact that in the 'French' suspension system load on the suspension cable insulation is significant, the French standard designed smaller spans between supports, and as a consequence – more linear-coupling valves. In the 'Finnish' air suspension system contact reinforcement with the bare suspension cable is more reliable – it can increase the anchor and the intermediate spans, which makes it possible to reduce the number of fixtures, which yet is more expensive. Manufacturers CIP in Russia went on to have developed their own systems and additionally produce CIP-1A – analog system with an isolated zero (Torsada), but the isolation of a thermoplastic polyethylene and STS-2 – analog system with a 'naked' zero (AMKA), but the isolation of silanosshivaemogo polyethylene. In the 'Swedish' system (ALUS, EX) – carrying wire is missing, and the suspension system is provided for all conductors simultaneously, ie mechanical load is uniformly distributed between zero and phase conductors, which gives the system a higher mechanical strength than the 'Finnish' and 'French' systems. Just 'Swedish' system is not only the most reliable and economically beneficial. Prices for wire STS-4 at 10% below value similar to the selected cross-section with carrying neutral wire. The fact that the reasons for making the systems do not require any special treatment rather expensive process of the alloy. In this case, price reduction is not achieved the deterioration of qualities (characteristics of CIP-4, by contrast, is much better than in systems with a suspension cable), but only the use of advanced suspension systems. Anyway, all three suspension systems Air insulated wires are successfully applied, and the choice is, ultimately, for consumers.
