The dry type current transformer Description

The dry type current transformer employs a Class F epoxy resin compound with fillers that undergoes vacuum degassing treatment before being injected into fiberglass mesh-reinforced coils for curing, resulting in significant improvements in mechanical strength, electrical performance, and thermal endurance. The insulation material features flame-retardant, explosion-proof, and pollution-free properties, effectively addressing end-users' operational concerns. It is suitable for power distribution applications in urban grids and is primarily designed for use in high-rise buildings, commercial centers, airports, offshore drilling platforms, ships, tunnels, large hydropower stations, railway stations, and similar applications.

Three phase dry type transformer

Dry cast resin transformers

Structure of Dry-Type Transformer

The core is made of high-quality cold-pressed grain-oriented silicon steel sheets with 45-degree fully inclined joints and five-step stacking method. Both the core columns and yokes adopt multi-stage circular cross-section shapes, which can achieve lower no-load loss and lower noise.

According to the dry type power transformer capacity, high-voltage conductors use double-glass enameled copper wires with H-grade fiberglass cloth and fiberglass mat insulation between layers; low-voltage uses copper foil winding with epoxy resin pre-impregnated cloth insulation between layers, featuring high mechanical strength and sudden short-circuit resistance.

The clamping parts adopt a low-magnetic steel tension plate and clamping structure, with sandblasting and spray coating treatment, presenting an aesthetically pleasing overall structure with high mechanical strength.

Each phase of the three-phase resin-cast insulated dry-type power transformer is equipped with an independent fan and separate temperature controller, effectively reducing temperature rise, increasing transformer output capacity, and ensuring safe operation of the transformer.
