Detailed Description

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, it is parallel 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 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 who has low lightning proof level and has high lightning tripping rate; hills and mountainous areas where 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 limit before entering into the transformer substation; seriously polluted areas.

Condition of use

Ambient temperature shall be within-40℃~+40℃;
Altitude shall not exceed 2000m (give clear indications when placing order for plateau areas)

Frequency of power supply is 48Hz~62Hz;
Max wind velocity shall not exceed 35m/s;

5.Areas where the seismic intensity up to and including Ms7;

Swing of Lightning Arresters is permissible, shall consider the suspension mode and stake mode according to the tower shape.

Using selection for AC Transmission Lines Arrester

Arresters for AC transmission and transformation lines can be divided into arresters without gap and arresters with series gap, arresters with series gap can also be divided into fixed gap arresters and air gap arresters, they have respective features in use.

Arresters without gap always take part in line running, it works when there is lightning strike on the line, it also will absorb various over-voltage energy on the line in normal state, but when the arrester has fault and is failed to work normally, it makes the bus grounded, shall cut off the power supply and remove it by manually. We have developed the series disconnector system for the arresters without gap, when the arrester is failed, disconnector would work automatically and let the arrester disconnect from the bus, it is convenient for customer to use and maintain.

Arresters with series gap will not take part in line running, which prolongs its service life, it discharge electricity when there is lightning strike on the line. Fixed gap arrester has advantage of stable discharge voltage range, but it will be equal to arrester without gap once the fixed gap is nonserviceable advantage of the air gap arrester is that it will always be disconnected from the system under normal state, the arrester gap will discharge electricit when there is lightning strike on the line, but its gap will swing along with the wind, and the gap discharge voltage range is not stable. Our company has developed the arc-shaped gap to overcome the problem of gap distance changes due to swing to the extent.
