Frequently Asked Questions (FAQ)

Q:What are your competitive advantages?

A:10-year warranty, CE certified, delivery within 1 month, drawings available in 2 hours, 24/7 online support. Excellent supplier for Schneider Electric and TBEA. Supports OEM/ODM/customization.
A:Dry-type transformers are oil-free and do not have the risks of oil leakage or explosion. They have high fire safety. The volume is relatively small, making them easy to install in the distribution rooms of buildings. The maintenance is simple and they meet the fire protection and space requirements of high-rise buildings.
A:Reasons: Loosening of core, deformation of windings, resonance of components, failure of cooling system, influence of grid harmonics. Measures: Tighten the core clamps; Correct the position of windings; Adjust the shock absorption devices of cooling fans / oil pumps; Install soundproof covers; Address grid harmonics.
A:The positions of the transfer switch are inconsistent; there is a short circuit between the windings (in a certain phase); the three-phase load is severely unbalanced; the system voltage is unbalanced across the three phases.
