ZCW10-40.5L

Open  air type  assembled switch gear

□Meaning of type

□Introduce

□ZCW10-40.5L-type open-type combination of electrical appliances is the use of air as the outer insulation SF6 gas as the interrupter medium complete sets of electrical appliances.For three-phase AC72.5KV power transmission and distribution system control and protection can also be used to contact the circuit breaker and opening and closing capacitor group of occasions.Suitable for land tension city

substation,enterprise substation,mountain substation.

□Characteristic of structure

□The breaker has the characteristics of small,outdoor type and with the console pot structure.It can match with CT35 spring operation mechanism.The spring operation mechanism associates with the main body,so the installation and debugging are convenient.Also it can be operated frequently and the mechanical life is not less than 10000 times.

□The breaker uses pneumatic arc-extinguishing chamber,so the breaking performance is excellent.The 40kA accumulative breaking times can reach to 12.

□The seal performance is reliable.The breaker uses imported sealed rubber insert.The dynamic seal uses structure of V shape grommet with spring pressure. The secondary terminal block is offered by the manufacturer as a set with the breaker to make sure that the annual leak rate of SF6<0.5%.

□The iron core of the inner current transformeris made of materials with the performance of crystallite(alloy)high conduction magnetic.So the accuracy class can reach up to 0.2 or0.2S.12 pieces of current transformers can be used inside as the clients'requirement.And it will not re-burn when switch zero load for 50kms
