Product Description

MEGATRO electric steel 230 kV substation  structures
MEGATRO provide design and fabrication of 230KV substation framework for our overseas clients.
230KV substation ramework was made of angle steel, square pipe, channel steel or others. Our 230KV substation framework has features as follow:
Custom designed to meet your dimensional requirements
Certified drawings & calculation package provided
Galvanized to ASTM A123
Design codes and specifications:
Industry: NESC, IEEE standard 605, and ASCE Manual 113
Wind: Per 2009 IBC & ASCE/SEI7-05
Seismic: Per 2006 IBC section 1613, ASCE 7-05 section 15.1.3 &12.8


Welding: ANSI/AWS D1.1-06
In material, we adopt high strength steel such as ASTM A572 GR50, GR65, Q420, Q460, S355J0, S355J0, Fe510, ST52 or other equivalent steel to meet project requirements. MEGATRO can optimize design and make 750KV,800KV,1000KV substation framework by solid, high strength, proper span distance, good wind resistance material, and economy in the use of materials.
After fabrication all 750KV,800KV,1000KV substation framework, are delivered to the galvanizing facility to be Hot DIP Galvanized. 750KV,800KV,1000KV substation framework is processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free structures.
