Substation steel structure is a rigid framework assembly used to suspend conductors, support conductors or switchgear, and other electrical equipment. According to usage, it can be divided into feeder racks, busbar racks, central door-shaped racks, angle racks, transformer combination racks, and single-pole equipment brackets. Generally, there are two types: steel pipe columns, and a framework with a horizontal beam consisting of equilateral or equilateral triangular section steel pipes; lattice-shaped steel columns, lattice-shaped rectangular or triangular section beam structures.

According to the nature of electricity, maintaining an appropriate distance between conductors, conductors to ground, and conductors to structures is required. Therefore, the distinctive feature of the gantry tower substation framework is its tall columns and small cross-section, making it a highly flexible structure. The gantry structure substation by electric tower manufacturers has strong load-bearing capacity, a lightweight design, and is easy for construction and installation, but requires regular maintenance.
1. Materials can be tailored:Q355B/A572, minimum yield strength>=355MPA; Q235B/A36, minimum yield strength>=235MPA, etc.or as equivalent.
2. Manufacturing and Process:Chinese national standards: GB/T2694, DL/T646
3. If need,both load test and destructive test can be offered and conducted by government;
4. Quality control: we stick to ISO 9001 system and do QC inspection for raw material, trail assembly test before mass production, dimension verification, galvanization test and issuing factory report before shipment for the both quantity and quality.
For each product, our steel tower manufacturers will do trail assembly to make sure all the dimensions are correct. If no, we will verify before mass production. All substation gantries will be fabricated without any flaw on the dimension and surface.
