JE researches, develops, produces and provides various dry-type power transformers, distribution transformers, grounding transformers, arc suppression reactor and other special dry-type transformers as well as non-standard dry-type transformers and dry type reactors and so on.
a. Encapsulated coil dry-type transformer
Purpose:
Applicable to industrial and mining enterprises and power system users that have high power quality requirement, high environmental requirement, and fireproofing requirements
Features:
1. Safe, nonflammable, fireproofing, can be installed directly on the load center;
2. Maintenance-free, easy installation, low operating cost;
3. Moistureproof, and can be operated normally under 100% humidity;
4. Low loss, low noise, small amount of partial discharge, and a loss usually 5%~10% lower than the corresponding national standard;
5. Good heat dissipation, strong overload capacity, allowing 50% overload in air-cooling condition;
6. Reliable, good temperature protection control system ensures safe operation of the transformer;
7. Small size, light weight, stable structure, strong capability in resistance to sudden short-circuit.
Production type:
On-load/non-excitation joystick transformer, foil winding epoxy encapsulated dry-type transformer, dry type distribution transformer, rectifier transformer, traction transformer, grounding transformer, reactor, and cubicle substation.
