20kv10kv6kv Waterproof Fully Sealed Fully Insulated Buried Transformer Underground Substation Embedding Type Transformers Impregnated Buried Transformer

Buried Distribution Transformer

Features:

S11-MD-underground distribution transformer core cold-rolled silicon steel miter joints using low-loss step-stack

from the system. High and low voltage coil using cylindrical and spiral wound structure. Transformer low voltage

side of the watertight box structure using high-pressure side of the head with waterproof cable products with

anti-pollution, water and strong, no-load current, low noise, low loss, low temperature characteristics, the

product can be charged continuously run for a certain time soaking advantages. Advanced technical indicators,

unique structure, exquisite appearance, is particularly suitable for a water environment such as underground

tunnels of a high-tech, high-performance energy-saving products.

The transformers can be buried underground in pits ,and can meet the needs of single ring high -voltage power

supply,applies to long distances but small loading system ,such as roads ,bridges,and tunnels.
