The tower weight and dimensions are confirmed when the detail drawings are issued for the wind and ice region of the site.
The specific brand is selected according to the route design. Send us a list of supports. We will confirm the availability and calculate it.
ЛЭП 330 kV supports are latticed metal structures made of sheet and angular rolled products, supporting wires and lightning protection cables of the overhead line. The 330 kV class is used for power distribution within large power systems and power supply to remote consumers.
The type of support is determined by its role on the track. The intermediate ones are placed on straight sections and only support the wires, the anchor-angled ones perceive the full weight on turns, the transition ones lead the line through obstacles, the terminal ones close it at the substation.
Anticorrosive protection is hot—dip galvanizing according to ГОСТ 9.307-21, the service life of the structure is at least 50-70 years. We manufacture according to standard designs and according to customer's drawings, and ship across Russia and to the CIS countries.
We receive the schedule, questionnaire or structural drawings.
We select the types for the route and climatic region and calculate the cost.
We issue working drawings and manufacture the structures with hot-dip galvanising.
Shipped as sections by road or rail.
Intermediate, anchor-angular, transitional, and end supports are manufactured in this class. The type is selected according to the role of the support on the track: the intermediate one only holds the wire, the anchor-angular one perceives its full tension, and the terminal one closes the line in front of the substation.
The letter code is the type of support (P, PS, U, US, AU, K, KS, PP), followed by the voltage class. The letter "T" means a cable stand with two cables, "P" means the transfer of the wires of the tier to the middle one. The number after the hyphen is odd — the support is single—chain, even - double-chain. "+" is the height of the prefix.
The mass depends on the type, height and design loads and becomes accurate after the release of the drawings КМД. The cost is calculated based on the weight of the metal, the grade of steel and the volume of the batch — we will give a guideline for a standard project immediately after specifying the grade.
Yes. We work on standardized standard designs for the voltage class and according to the customer's drawings КМ. In this case, we produce working drawings КМД and produce according to them.
Send the tower schedule or the route parameters — we will select the types and prepare a calculation.
