High Voltage AC Load Breaker Switch
Product description
FLN36-12 type indoor high voltage AC load breaker switch refer to international new technology and develop the switching equipment in according to the relevant standards in China's electric power system. It’s performance indicators in full compliance IEC420. 694.129 and national standards GB3804-2004"3.6k-0.5Kv high voltage AC load breaker switch" GB1985-2004" high voltage AC isolation switch and earthing switch" GB/ T1 1022-1999" common technical requirements for high-voltage switchgear and control equipment standards" . This is the main switching element RMU. The load breaker switch is a multifunctional medium voltage switchgear of gates, sub-gate. earthing. in a fully sealed with strengthen the structure of the epoxy resin housing to filled with SF6 gas,0.05MPa, with the minimum parts to achieve the above three functions. to ensure product quality, improve reliability, maintenance-free can be safely run for more than 20 years in normal conditions.
High Voltage AC Load Breaker Switch Operating conditions
Environment condition
1. The altitude: under 1000M.
2. The ambient temperature: -25°C-+40°C
3. The relative humidity of air: monthlys90%, dailys95%.
4. Amplitude: Earthquake degree 8.
5. Application occasions should free from fire, inflammables, explosives, corrosives and severe vibration.
Feature
Product Parameter (Specification) of 24 Cores Single Jacket All-Dielectric Self-Supporting (ADSS) Optical Fiber Cable
1. Load breaker switch adapts double fracture, rotary movable contact structure, with the following three kinds of operating states. Closing, opening, earthing.
2. Uusing SF6 gas as an arc extinquishing and insulating medium, the main circuit seals by the upper and lower housing pouring epoxy rein the conductive function is unaffected by external influences.
3 .Good safety performance. If internal arcing occurs. the housing has an internal structure weak point, it will be rushed to open. followed by
