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.
