The Pole-mounted Loadbreak Switch designed and engineered by BKE Electric Company possesses the following characteristics: high safety and reliability, longevity, easy to operate, low maintenance and simple installation. Our switches can be manually or motor operated. Its output terminals are accessible by any standard RTU (Remote Terminal Unit) or FTU (Feeder Terminal Unit) and the units can be integrated easily to a full scale SCADA (Supervisory Control And Data Acquisition System).

　　
　　Our pad-mounted switch uses as the insulating medium. Housed inside stainless steel enclosure, our unit is free from intrusions from unauthorized personnel and is disaster proof in almost all weather conditions. The safe operation mechanism, and motor and manual mechanism are sealed in the tank that ensures corrosion free. The enclosure has interlocking and low pressure locking devices, offering automatic controller that is accessible for tele metering and remote control. Communication methodology can be direct cabling, radio, broadband, or Internet. Our unit can be easily integrated to a DA system, transmitting data back and forth to the master station, controlled remotely or locally.

　　ZW32 Outdoor Pole-mounted Vacuum Circuit-Breaker implements the sealed mechanism in accordance to the IV Grade requirement. The circuit breaker can be assembled with spring operating mechanism or permanent magnetite operating mechanism. The spring operating mechanism is small, simple, light and reliable, with low-loss power-reserving motor. The permanent magnetite mechanism has only a few movable components, requiring only minimum operating power; therefore it is almost maintenance free and, as in the case of spring-operated unit, can be integrated into a distribution automation system. BKE's Circuit Breaker can be used as a recloser when equipped with a reclosing controller. A recloser plays a critical role in a modern distribution automation system.

　　
　　BKE's switch is in a sealed structure, to protect the switch from dumping and dew in high-temperature and damp areas. The stainless steel enclosure ensures rusty free in the outdoors.
　　The insulting sleeve of circuit breaker is made of imported, top-grade epoxy resin and modules for outdoors by APG. BKE is proud to be the first Chinese manufacturer to successfully make the sleeves and its patent is pending. The epoxy resin enhances the insulating stability in damp, thus the products can be operated most reliably in any adverse circumstances. The vacuum arc-extinguishing chamber and CT are sealed in the sleeve to ensure the high electric insulation, resisting dew.
　　In order to add viewing-break，we can install a disconnector at the coil-out of the circuit breaker. There is a mechanical interlock between the disconnecting knife and circuit breaker to prevent incorrect operation.
