HY5WZ-3~6kV

HY5WZ-3~6kV arrester is specially designed for 3kV-6kV low-voltage distribution system. It uses high-performance zinc oxide valve (ZnO) and anti-aging silicone rubber composite jacket to effectively restrain lightning and switching overvoltage and reduce line tripping rate by 55%+. Compliant with GB 11032-2000 (equivalent to IEC 60099-4) standard, fully sealed maintenance free structure, capable of withstanding environmental temperatures ranging from -30 ° C to+60 ° C, resistant to moisture and chemical corrosion, with a lifespan of over 20 years. Suitable for low-voltage distribution cabinets in factories, power supply systems in commercial buildings, and small rural substations, especially suitable for scenarios with limited space and poor maintenance conditions.

Description

Organic polymeric housed Zinc oxide arrester for AC transmission and transformation lines is a new type arrester specially designed for reducing the tripping rate of system caused by lightning fault, and it is parallely connected on two sides of insulator (string) to limit the lightning over-voltage and improve lightning proof level of lines. Main installation mode is suspension type (suspend on the power transmission tower), also stake type installation is available.

The polymeric housed metal-oxide arresters (suspension type, stake type) for lines produced by our company are mainly applied to power transmission and transformation systems of AC 10~ 220kV, used to limit various over-voltage situations that may arise in power transmission and transformation circuits, guaranteeing safety running of power transmission and transformation lines.

Executive standards for production of the products are GB11032-2000(eqvIEC60099-4:1991) Metal oxide surge arresters without gaps for a. c.systems, JB/T8952-2005 Polymer-housed metal oxide surge arresters without gaps for a.c. systems, JB/T10497-2005 Polymeric housed metal oxide surge arresters with series gap for a.c. electric power transmission line,JB/T8459-2006Designation for surge arrester products.

Product Feature

It is made by moulding at a time from a model, good sealing performance, special structure, dampproof and explosion-proof;
Good heat dispersion, strong over-voltage absorption capacity;
Compact volume, light weight, flexible installation,crashworthy, high tensile strength, will not be damaged during transportation.
It is most suitable for transmission lines which has low lightning proof level and has high lightning tripping rate; hills and mountainous areas which are droughty and rainless; towers of high earthing resistance and cross-river towers of large span; occasions have high operating over-voltage and need to be limited before entering into the transformer substation; seriously polluted areas.
