Product Description

Outdoor 110KV High Voltage Sulfur Hexafluoride SF6 Circuit Breaker LW39-126 / 3150A

Description

LW39-126 outdoor AC high-voltage porcelain column SF6 circuit breaker can be used in power systems with a frequency of 50Hz and a system nominal voltage of 110kV. It is the main power equipment used for control and protection in power plants and substations. The circuit breaker adopts the principle of thermal expansion self-energy arc extinguishing, and is filled with SF6 gas with excellent arc extinguishing performance and electrical insulation performance. All seals use double-ring O-rings to effectively prevent gas leakage. It is equipped with a CT30 spring operating mechanism to realize three-phase mechanical linkage operation.
Product features:
Stable breaking performance, can reliably break short circuit, out of step, near zone and other faults at the outgoing line end;
The arc extinguishing chamber has a simple and reliable structure and is easy to maintain;
Long electrical life, with the ability to break 20 times at full capacity, and maintenance-free for 10 years under normal operating conditions;
Small operating force, using a simple and reliable compact spring operating mechanism;
Low rated gas filling pressure, can adapt to low temperature conditions;
Small footprint;
Low noise level, suitable for residential areas;
Long maintenance cycle, less maintenance workload;
Short on-site installation and commissioning time.
