Main features
1. Compact structure, fully sealed structure, safe and reliable, name maintenance, reliable protection of personal safety.
2. The high-voltage wiring can be used for both the ring network and the terminal. The conversion is very convenient and the reliability of the power supply is improved.
3. Excellent transformer performance: low noise, low loss, strong impact resistance, short circuit and overload resistance.
4. The car body can adopt anti-corrosion design and special painting treatment according to the requirements of the operating environment, and can meet the anti-corrosion requirements in high temperature and high humidity environments.
5. It is widely used in outdoor places such as urban power grid transformation, residential quarters, high-rise buildings, industrial parks, factories, temporary construction electricity, airports, oil fields, docks, highways, etc.
Features
1. Small size, compact structure and convenient installation;
2. It can be used in ring networks and terminals to reliably protect personal safety;
3. low damage, low noise, superior performance;
4. The box body adopts anti-theft structure;
5. Low temperature rise and strong overload capacity.
Advantages of American box change
Advantages: small size, small area, easy to place, easy to camouflage, easy to coordinate with the environment of the community. The length of low-voltage cables can be shortened, the line loss can be reduced, and the cost of power supply matching can be reduced.
