24kV Pole-Mounted Load Break Switch

ZWF-24/630-16

24kV Pole-mounted load break switch is vacuum interrupted, solid insulated, and three poles design. It is designed and tested according to standard IEC62271-103, mainly for overhead lines on 24kV distribution network to transmit and interrupt the load current, instead of cutting the short circuit false. It is also can be used to isolate the false, minimizing power outages area and improving power supply reliability.

Product introduction:

In the 24kV pole mounted load break switch, we encapsulate the vacuum interrupter, main circuit live parts, high-accuracy voltage and current sensors, and high voltage pickup capacitors inside the three cycloaliphatic-epoxy poles, based on decades of experience in solid insulation technology. The switch has 6 voltage sensors to pick up power source side and load side voltage, 3 current sensors to pick up three-phase current.

The three phases of the pole mounted load break switch are driven by independent magnetic mechanism respectively, which reduces dispersion, responding more timely and breaking more accurately. The LBS is equipped with electrical latching and manual open and close handle, which latch electrically and manually the closing when the breaking handle is placed in the open position. A mechanical counter is installed at the bottom of the switch for counting the number of switch operations.
