Product Details

FLN36-12KV FLRN36-12KV High Voltage SF6 Load Break Switch

Product Description

SF6 puffer load break switch

FLN36-12combination, SF6 load switch Used to open and close the load current and no-load long term and no-load transformer, control, protection of transformer or high voltage motor.

After add intelligence unit which can realize remote control, meet the requirements of distribution automation.

FUNCTION

1. The load break switch, isolating switch, earthing switch are sealed in the SF6 body, the relative press of the SF6 is 0.04MPa.

2. Three function in one equipment: this switch are fulfill with the switch off the load current, isolated and earthing.

3. Operation Safety: a. The switch can only one of three positions, can avoid misoperation. b. There is a safety diaphragm of the insulating box, this can directional release the pressure backward. c,There are two windows on the body, for explore. d,The sensor of the electric display e,The mechanism is made by the spring, have stable function

4,the good arc extinguishing and switch off function: a.The fuse combination's rated transfer capacity is 1500A b,The switch can switch when the pressure is zero c,SF6 has good arc extinguish function d,Long electrical endurance

5,good insulating function: a.SF6 has good insulating function b,The insulating body are made by epoxy resin, produce by APG c,Admirable insulating function, air leak rate less than 0.5% per year.

6,Blocking design, has more compact structure, can use for many situation.

7,Can apply with the electric motor.
