High Voltage Limit Current Fuse can be used in system with AC 50Hz and rated voltage of 10KV, used together with other protection electric facilities such as loading switches. It can protect power transformers and other power facilities against overloading or circuit break. It is mainly used in American style transformers as backup protection.

It is a kind of metal hardware, commonly known as spring pin and safety pin. It is made of high quality steel and elastic materials.

The dry-type transformer consists of an iron core composed of silicon steel sheets and a coil cast with epoxy resin. An insulating cylinder is placed between the high and low coils to increase electrical insulation, and the coils are supported and restrained by a pad. 
Because epoxy resin is flame retardant, flame retardant, self-extinguishing solid insulating material, that is, safe and clean. With oil-free, inflammable, low operating loss, outstanding disaster prevention ability, it is widely used in high-rise buildings, airports, wharfs, power plants, residential areas or complete substations and other places.

VS1- 12 (ZN63-12) side-mounted type vacuum circuit breaker is a kind of indoor high voltage switch device which is used in the AC thee-phase power system of frequency 50/60Hz. rated voltage 12KV to be the protection and control unit. Because of the special superiority of vacuum circuit breaker, especially suitable for applications that require frequent operation at rated operating current or multiple open short-circuit breaking curent location. It is especially suitable to the place requiring frequent operations.
VS1- 12 (ZN63-12) side- -mounted type vacuum circuit breaker adopts fixed insallation, which is mainly used in the fixed switchgear. It can be used alone or used in ring network power supply system, box-ype variable system and non-standard power supply system to protect and control the Tansmission and disribuion line.

 ZN63(VS1) indoor high-voltage alteratingcurrent vacuum circuit breaker has a frequency of 50Hz and a rated voltage of 12kV. It applies to the ecrical equipment control and protection in industial and mining enterprises, power plants and substations, priculanty to the places needing frequent operation. It can be fixed in a switch cabinet or nstalld on a handcart.
 With stable performance and convenient intallation, it is the best choice for the control and protection of hig-voltage power transmission and distribution systems.

Apply to industrial and mining enterprises, substation and transmission and distribution systems for control and protection switching; particularly suitable for metallurgy. electric arc steel-making industries, elc. frequent operation required, as a control and protection equipment.
ZN23-40.5 Series meet GB1984-89<AC HIGH VOLTAGE CTRCUTT BREAKER> Standards.

 VF(R)-12 indoor embedded high-voltage alternating-current vacuum load switch-fuse combination (“vacuum load switch" )is a new generation vacuum switching equipment developed based on unique design ideas to meet the market demand. It is widely used for indoor armored air-insulated switch cabinets. In normal conditions, it can operate within its technical parameters in any grid of the specified voltage level safely and stably.

The primary purpose of any fuse cutouts is to provide protection to the lines of your system and the various apparatus on those lines such as transformers and capacitor banks. Fuse cutouts provide reliable protection from low-level overloads that just melt the fuse link, intermediate faults, and very high faults, through maximum interrupting capacity.
