Product Description

Product Description

Transformer

Dry-type transformers utilise epoxy resin casting or vacuum impregnation processes for insulation. Their oil-free design offers the advantages of fire resistance, flame retardancy and zero pollution, making them suitable for indoor environments with stringent safety and environmental requirements, such as commercial complexes, residential estates, hospitals, data centres and rail transport stations. Both product types feature high-quality cold-rolled grain-oriented silicon steel core and high-strength insulated windings, combined with advanced manufacturing processes and multi-layered safety protection designs. With voltage ratings ranging from 10kV to 35kV and a comprehensive range of capacity specifications, they can meet the power supply requirements of various industries and scenarios, providing a reliable guarantee for the safe, efficient and economical operation of the power grid.

Rated high voltage	11,10.5,10,6.6,6.3,6kV
Insulation class	F/H
Insulation level	LI75AC35/AC3
Link group code	Dyn11/Yyn0

Highly efficient and energy-saving, with a low-loss design

The core utilises high-grade cold-rolled grain-oriented silicon steel sheets, combined with an advanced multi-stage step-stacking process, which effectively reduces magnetic circuit losses; no-load losses are reduced by 15% to 30% compared to traditional products; The windings are wound with high-quality oxygen-free copper wire. Through optimised winding structure and wire cross-section design, Joule heating losses during current transmission are minimised. The overall energy efficiency far exceeds the national Class II energy efficiency standard, with certain models meeting Class I energy efficiency requirements.

Safe and reliable, with multiple layers of protection

Having passed rigorous type tests, including lightning impulse tests, short-circuit withstand tests and temperature rise tests, the equipment is capable of withstanding harsh environments such as high temperatures, high humidity and high dust levels. It ensures stable operation even under complex conditions such as power grid fluctuations and sudden changes in load, significantly reducing the risk of equipment failure and downtime, and providing a robust safeguard for the safe operation of the power system.

Environmentally friendly and suitable for a wide range of scenarios

Featuring a low-loss, low-noise core and winding design, it minimises electromagnetic radiation and vibration noise whilst offering excellent resistance to moisture, dust and corrosion. Suitable for a wide range of environments—including outdoor substations, industrial sites, commercial complexes, residential estates, hospitals, data centres and rail transport stations—it meets the dual requirements of power supply and environmental protection.

Durable and easy to maintain, with low total cost of ownership

All products are designed to have a service life of over 30 years. Under normal operating and maintenance conditions, the failure rate of the equipment is extremely low. For oil-immersed transformers, the service life of the insulating oil can be extended through regular oil sampling and filtration; dry-type transformers, on the other hand, require virtually no replacement of the insulating medium, thereby significantly reducing maintenance costs and downtime for users.
