Overview
Pole mounted insulation load break switch, type GPS-24/630-20 is suitable for the rated voltage 24kV,rated current 630A,50/60Hz power grid open circuit,load current in closed Power system,overload current. This load break switch can separate those broken distribution line automatically. With the latest technology, it has the newest electronic controller.The switch can be used by manual operation, electric operation and operation from a long distance. Electronic controller is installed in a stainless steel cabinet which is suitable for using under all kinds of climatic conditions. In addition, there are some wired and wireless modem installed in the cabinet through which it can realize the remote monitoring and control. Simple installation on pole is convenient, fast, and also can reduce the construction cost.

Features Features
3.1 SF6 gas-insulated
3.1.1 SF6 gas is a kind of nontoxic, nonflammable and electrical insulating gas. It has the excellent characteristic of arc extinction.
3.2 Drive pipe with large diversity
3.2.1 In addition to the standard ceramic drive pipe, we can also provide a variety of solutions, including rubber insulators used in the epoxy resin filling equipment.
3.3 Visible open / closed status
3.3.1 It is easy to see the main contact position indicator which is color-coded just standing on the ground (Green - off; red - closed). The indicator is directly connected with the main contacts of the drive shaft assembly to ensure accurate display of contact states.
3.4 Quick operation
3.4.1 operating mechanism with spring energy to ensure a quick closing and opening operation (less than 100milliseconds). 3.5 Can realize remote control
3.5.1 It is equipped with electronic controller, fit for in situ operation as well as FTU interface console operation.
3.6 Rugged switch
3.6.1 The switch is made of proven durable, corrosion-resistant materials (special used in warships 304L stainless steel plate)which ensures that there is a very long service life (30 years), and can be implement a series of operations.It has the ideal characteristics as a column equipment.
3.7 Standard
3.7.1 Each switch before leaving the factory has been filled with SF6 gas, sealed, and test according to IEC60265-1, GB40.504 standard.
