Binzhou Hongbo Electric Co., Ltd. was incorporated in 2009, is located in Binzhou City, eight the Yellow River Road No. 856, is a set of production and manufacturing, sales and installation of integrated enterprises diversified electric power equipment business.
Main business: 10KV, 35KV high and low pressure electrical products, electrical materials, fittings, wire and cable, electrical and mechanical hardware, rubber chemical products, welding materials, labor supplies, electrical materials, steel pipe fittings, sundry products, lamps sales; prefabricated substation, high and low voltage power distribution cabinet, control cabinet, distribution box processing production, distribution, electrical equipment installation.

Structure Features
Type XL-21 low voltage control cabinet is of enclosed type and its case is made of stainless steel.The operation handle is installed at the upper part of right pole for power switching one voltage meter is installed in the front distribution case to indicate bus voltage.The front of the distribution cabinet has door which,in case of opening,keeps the parts in the cabinet exposure for convenient maintenance.
This distribution cabinet adopts domestic parts and has such features as compact structure,easy maintenance and flexible combination.The distribution cabinet,in addition to the air curcuit breaker and fuse as short circuit protection,also installs contactor and thermal relay.The operation button and indication light are installed in the front door.

Application

XL-21 motive electricity switchgear cabinet is suitable for three-phase four-wire power system with AC frequency of 50Hz and voltage of 380V. Widely used to the low voltage power distribution systems of power plants, transformer substations, petroleum, chemical, metallurgical, machinery and other industrial enterprises and high-rise building for power transformation, distribution and controlling.
