Product Features:
The core adopts RIP structure, which has a high insulation and heat resistance level, and avoids the long-term operation and aging of the insulating material.
The automatic winding machine is used to wind, and the proportion of insulation in the core is high, which effectively improves the distribution of the electric field of the external insulation under harsh working conditions.
Excellent waterproof and leakage resistance.
It has high mechanical strength and meets the requirements of class VIII seismic resistance.
Oil-free, not easy to explode, fire and other phenomena after failure, high safety and reliability;
Excellent insulation performance and maintenance-free.
Can be used at high altitudes;
It can be used in heavily polluted areas.
We offer the most advanced engineering design solutions and product technology solutions to global power customers, and continue to create value for the commercial success of global power customers.
