Class H Impregnated Dry-Type Transformer
Description
● This product is classified as Class H (180°C) insulation, with its primary insulating material being Class C (220°C), providing robust overload capacity. Under sustained overload conditions, it may operate continuously at 120% of its rated capacity.
● no partial discharge and "cracking" during operation.
Product Introduction
This product is an H-class high-temperature resistant vacuum impregnated dry-type power transformer. It features fully insulated high-temperature resistant structure, oil-free explosion-proof and fire-retardant performance. Its safety level is much higher than conventional distribution transformers, and it is widely used in high-voltage indoor power distribution scenarios such as high-rise buildings, hospitals, commercial complexes, residential areas, new energy power stations and industrial plants.
Core Product Advantages
1. Ultra-high temperature resistant insulation
Adopt H-grade insulating materials, with rated heat resistance up to 180℃. It keeps stable insulation performance under long-term high-temperature operation without aging, and has excellent overload resistance and longer service life than ordinary epoxy dry-type transformers.
2. Vacuum impregnation & curing technology
Whole winding adopts vacuum high-pressure impregnation of high-temperature resistant insulating varnish. It has outstanding moisture-proof, mildew-proof and pollution-proof performance, stable operation in humid and high-salt-fog environment, and strong resistance to short-circuit impact.
3. Ultra-safe fire protection performance
Fully dry and oil-free design, non-flammable, non-explosive, no oil leakage risk. It releases no toxic smoke in fire accidents, fully meets strict fire protection codes for crowded places and high-rise buildings.
4. Low noise, energy saving & maintenance-free
Low no-load & load loss, ultra-low operating noise, optimized heat dissipation structure. It runs stably with little daily maintenance, greatly reduces later operation and maintenance costs.
Application Scenarios
Urban power distribution, residential communities, commercial buildings, hospitals & schools, rail transit, photovoltaic & wind power stations, industrial workshops, data centers, underground power distribution rooms and other enclosed indoor power supply occasions.
