Load Break Switch (Solid)
Environmentally friendly polymer insulation and vacuum interruption
Switching on/off the load current of process power distribution line, for division and tapping of lines
- SF6 gas free
This product uses vacuum interruption and does not use SF6, a greenhouse gas, which makes it environmentally friendly.
By adapting a polymer insulation, it doesn’t require constant maintenance, gas monitoring or top up of insulation.
Through watertight epoxy mold, we’ve removed the danger of explosion due to rise in pressure.
Quality stability has been realized by Mold product that has the same shape.
- Operating part
All the point of contact in all planes open and close at the same time. The speed of opening and closing is always the same regardless of operation.
Automatic switch can be operated not just electronically from the control box, but manually by controls on the body. It can be operated on the spot or via a remote.
- Water proof & rust prevention
The body of the switch has been welded with stainless steel and covered with epoxy tar film, making it rust-proof.
- Compact design
A compact design was achieved through VI method and simple control, which minimizes the room needed for installation.
