Manufacture

In 2010-2011 the tests were successfully performed and production of variable cross-section metal poles of open profile was set up having some advantages over the analogs and permitting the customer to reduce the expenditures for installation and further maintenance.

Diacom Service, LLC products are of high-quality raw materials and have GOST R certificates confirmed by the certificate tests of the leading test centers and laboratories. The component parts included into the delivery set are thoroughly selected and also have certificates.

The coating of stand and metal structures provides their protection against corrosion up to 50 years.

The poles represent compactly packed sets and include multifaceted steel poles of open profile manufactured according to TU 5264-039-95973702-2010, metal structures – TU 5264 – 002 – 95973702 – 2010, insulators and a complete set of overhead line hardware, as well as metal products.

vThe poles are designed for operation in the populated and unpopulated area in the wind zones I-VII, glaze zones I-VII according to the Electrical Safety Rules (edition 7) at the design temperature of the coldest five-day period of minus 65°С and more. Under the geological and geophysical conditions the poles are designed for the districts with the regular construction conditions with seismicity up to 9 points inclusively and may be installed in all types of grounds with the porosity factor “e” from 0.45 to 1.05. Zoning of the territory of Russia is assumed according to SNiP 23.01-99.

Steel multifaceted stands of open profile

TU 5264-039-95973702-2010

The stands of open profile are included into the structure of poles produced according to TU 5264-040-95973702-2010 and designed for operation in the populated and unpopulated area in the wind zones I-VII, glaze zones I-VII according to the Electrical Safety Rules (edition 7) at the design temperature of the coldest five-day period of minus 65°С and more. Zoning of the territory of Russia is assumed according to SNiP 23.01-99.

Under the geological and geophysical conditions the poles are designed for the districts with the regular construction conditions with seismicity up to 9.

The climatic configuration of poles – UHL, category of location I according to GOST 15150.
