describe

ZBLBS-11-24-33/630-20 pole-mounted load switch is suitable for rated voltage 12KV/24kV33KV rated current 630A, 50/60Hz distribution network breaking and closing load current and overload current in the power system, which can be automatically isolated Faulty distribution line section. ZBLBS can be operated manually, electrically and remotely. The controller is housed in a stainless steel housing and can be used in all weather conditions. In addition, wired and wireless modems can be installed in the cabinet to realize remote monitoring and control. The simple pole-holding arrangement is convenient and fast, and reduces the construction cost.

advantage

1. SF6 gas insulation. SF6 gas is a non-toxic, non-flammable electrical insulating gas with excellent arc extinguishing properties.

2. Casing diversity. In addition to standard ceramic bushings, there are a variety of options including rubber insulators on epoxy equipment bushings.

3. Visible on/off status. Color-coded main contact position indicators (green - open; red - closed) are easily visible from the ground. The indicator is directly connected to the main contact drive shaft assembly to ensure accurate display of contact status.

4. Act fast. The spring stored energy operating mechanism ensures fast closing and opening operations (less than 100 milliseconds).

5. Remote control can be realized. Equipped with electronic controls, it can be operated locally or on the main console with FTU interface.

6. Strong and durable switch. Manufactured from proven durable, corrosion-resistant materials (304L stainless steel plate for warships), the switch ensures a long service life (30 years) and can perform a range of operations, making it ideal for pole-mounted equipment. feature.

7. Standards. Each switch has been filled with SF6 gas before leaving the factory, and sealed and tested according to IEC60265-1 (1988) and GB3804-1990 standards.
