KSG 500KVA 11KV/0.4KV Mine Type Transformer

Product Description

KSG series mine dry-type transformers are suitable for central substations, underground yards, general air inlets and main air inlets in coal mines. Metal and non-metal mines that have gas but no explosion hazard are used to supply power to various equipment in mines and underground mines, and are also used to power public railway tunnels.

Related Standards

The transformer is designed, manufactured and inspected in accordance with the relevant standards of GB1094, GB12173-2008, GB4208-2008, JB/T3955-2006, with KY and KA certification, and reliable quality.

Product Advantages &Characteristics

1. KSG mine dry-type transformers have the advantages of safe, reliable, energy-saving, fire-proof and explosion-proof, no harmful gases, no pollution to the environment, and simple maintenance.

2. Product performance indicators are superior, maintaining excellent electrical and mechanical properties during the entire service life. It is most suitable for environments with high fire protection requirements, large load fluctuations and high heat resistance levels.

3. The iron core of KSG mine transformer is made of high-permeability and high-quality cold-rolled silicon steel sheet, with small joints, low loss and low noise. The coil adopts the most advanced winding technology, and heat-resistant insulating materials are used between layers and turns. The insulation grades are F and H heat-resistant grades, which can be operated for a long time under a 180° environment.

4. The coil is vacuum dipped with imported paint, and the dipping paint completely penetrates the deep layer of the coil. 160℃~170℃ drying and curing, high mechanical strength. The body is vacuum-dried by variable pressure method, and the surface of the body is covered with a layer of anti-moisture paint, which has good insulation properties.

Specifications & Voltage Levels

The rated capacity of KSG mine transformer is 50~1600kVA, the input voltage is 11KV, 22KV or 33KV, and the output voltage is 1200V, 693V or 400V.
