4MVA 11/0.4kV 3 Phase 50Hz Dry Type Transformer

Overview

With filler thin insulation and coil encapsulated by epoxy resin, this series of dry type transformers is flame-retardant, fireproof, explosion-proof, free from maintenance and no pollution and it is compacted and can be installed at load center. Besides, with scientific and reasonable design and coating craftwork, it has advantages of low partial discharge capacity, low noise and good heat dispersion. It can run for a long time with 140%rated load in the circumstance of forced air cooling. It is also equipped with an intelligent temperature controller to conduct centralized monitoring and control.

IEC 60076-11: Power transformers – Part 11: Dry-type transformers
IEC 60529: Degrees of protection provided by enclosures (IP Code)

Features

Dry type power distribution transformers have low loss and good power saving which brings economical operation. They are flame-retardant, explosion-proof, non-polluting, maintenance-free and can be installed in the load center to reduce investment costs and saving costs. The dry type distribution transformer has a small partial discharge. The coil does not absorb moisture and dust which has high mechanical strength and good reliability. Dry type power distribution transformers are short-circuit resistant and have good lightning-impact resistance. If the user needs a temperature control and temperature display system what can be used with the temperature control system
