Product Features
Modular cabinet design
The cabinet features a modular design that can be disassembled and reassembled, making installation simple and fast.
Noise reduction
Through-core bolt structure effectively reduces operating noise with significant noise reduction.
Special process
Coils undergo multiple dip-varnish treatments for enhanced three-proof performance against moisture, corrosion, and mold.
45° Cold-Rolled Silicon Steel Sheet
The core is made of premium cold-rolled silicon steel sheets, precisely stacked at 45° full-miter angles to ensure high efficiency.
Cable gland design
The transformer tank is fitted with cable glands for cable entry and exit; gland positions can be arranged on the left or right side.
Moisture-proof and salt-fog resistant
Coils and insulation components receive triple-proof (moisture, mold, salt fog) treatment for durable operation in humid, high-salt-fog marine environments
