Technical Specs

Why Maotong for Substations?

Accuracy of ±0.3mm: We use CNC plasma cutting center to process the connecting plate, and the accuracy of key bolt holes is controlled within ±0.3mm.This way expensive insulator equipment can be installed smoothly, directly saving you valuable construction time, eliminating additional costs and delays due to modifications.

100% pre-assembly: Every complex structure is 100% ground trial assembled in our factory before shipment. We'll put all the pieces together and verify all the connections. This way you receive a complete 220kV Electrical Substation Gantry Equipment Support Structures that has been verified and guaranteed to be assembled, greatly reducing the uncertainty of field installation and lifting risks.

High adaptability: we use an average of 100μm or more thick hot dip galvanized layer, which is far beyond the ordinary standard.In corrosive environments, our structures provide corrosion protection for years, reducing your life-cycle maintenance costs and ensuring long-term grid stability.
