Detailed Description

Overview

LW16-40.5 outdoor sulfur hexafluoride circuit breaker is an outdoor device used in AC 50Hz three-phase power systems for control and protection of industrial and mining enterprises, power plants and substations. This product can be operated frequently and can be used as a connecting circuit breaker and a circuit breaker for connecting capacitor banks and reactor groups. The built-in Current Transformer can be used for measurement and protection. It can directly replace the SW2-35 low-oil circuit breaker. It can replace various types of high-oil Circuit breakers with overcurrent brackets. It is an ideal oil-free circuit breaker in 35kV power systems.

Note: When the circuit breaker is in hot standby mode, a Lightning Arrester must be installed on the road side of the break.

Working conditions and use environment

1. Altitude: not more than 3000m;

2. Ambient temperature: -25℃~+40℃;

3. Wind speed: not more than 34m/s;

4. Pollution level IV, creepage distance of porcelain sleeve: > 1255mm;

5. Places without flammable substances, explosion hazards, chemical corrosion and severe vibration.

Note: If the above requirements are exceeded, the user can negotiate with the manufacturer.
