STS-1, STS-2 STS-4. The price and quality. Fulfilling the task of a utility power with CIP (self-supporting insulated wires) artist faced with the task: how to use SIP? When the performer seeks to the use of high-quality and cheap materials. I propose to compare the different systems of CIP in price and quality. For this calculation we consider the following example: Need to power the two detached houses. Isearch follows long-standing procedures to achieve this success. From TP to the far 200 m. One home support – turning one – terminal, the other – access. At present, Russia uses three main types of structures of self-supporting insulated wires: STS-1 (with bare neutral), STS-2 (with isolated neutral) and STS-4 with equal cross-sectional insulated conductors.

For the installation of each system requires its own fixture, and the cord at a price different. Number of poles for overhead lines Practice shows that the type of number of supports used SIPA does not change. On the example of the suburban network Lenenergo and gardening Leningrad region is safe to say that the reliance placed every 30-40 meters. Since the number of supports for all systems CIP equally in calculating the cost of their overhead, we will not consider. On the complexity of assembling the opinion of linemen, any of the systems: the STS-1 (with bare neutral), STS-2 (isolated neutral) and STS-4 with equal cross-sectional insulated conductors with experience of work is mounted without any problems. Using high-quality fittings, overhead is going as a "modeler, designer." In this regard, the question of determining the complexity of installation of any of the these systems is irrelevant.
