Dry-type Transformer

Dry type Transformer is an oil-free power conversion equipment that relies on air or solid insulation materials for heat dissipation and insulation. It has the characteristics of fire and explosion prevention, high efficiency and energy saving, and is widely used in distribution scenarios that require strict safety and stability.
Core Features
1. Safety and environmental protection: No flammable or explosive insulation oil, using F/H grade flame retardant materials, complying with GB/T 1094.11-2022 A-level flame retardant standards, no toxic gas release during operation, and easy to recycle waste.
2. High efficiency and low consumption: in line with GB 20052-2024 first/second level energy efficiency, high magnetic conductivity silicon steel sheet+high-purity copper foil winding, significantly reducing no-load/load losses, and achieving considerable annual energy savings.
3. Stable and durable: The iron core is designed with fully inclined seams and elastic clamps, with an operating noise of ≤ 58dB, a local discharge capacity of ≤ 10pC, a short-circuit resistance of 30kA, a design life of 20 years, and no regular maintenance required.
4. Flexible adaptation: Small size, no need for a dedicated computer room, customizable protection level IP00-IP67, capable of stable operation in a wide temperature range of -30 ℃~60 ℃, high humidity, and coastal anti-corrosion environment.
main types
