I. overview

The organic compound coated zinc oxide arrester used in AC transmission lines is connected in parallel to the two ends of insulators (series). It is a new type of arrester specially designed to limit lightning overvoltage of lines, improve lightning resistance level of lines and reduce tripping rate of systems caused by lightning faults. Installation mode is mainly suspended (suspended on transmission tower) or pile-type installation. The compound coat metal zinc oxide arrester (suspension type, pile type) produced by our company is mainly used in 10-220 kV AC power transmission and transformation system, which is used to limit various kinds of overvoltages that may occur in transmission and transformation lines, so as to ensure the safe operation of transmission and transformation lines.

The standards for product production implementation are GB11032-2000 (eqv IEC 60099-4:1991), "AC Gapless Metal Oxide Arrester", "JB/T8952-2005" Composite Coat Gapless Metal Oxide Arrester for AC System","JB/T10497-2005"Composite Coat Series Gap Metal Oxide Arrester for AC Transmission Line", "JB/T8459-2006" Method for Making Product Types of Arrester.

II. Product Characteristics

1. Integral moulding, good sealing performance, special structure, moisture-proof and explosion-proof;

2. It has good heat dissipation performance and large over-voltage absorption capacity.

3. Small size, light weight, flexible installation, anti-collision, high tensile strength, no damage to transport.

4. It is most suitable to install transmission lines with low lightning resistance and high lightning trip-out rate; hilly and mountainous areas with drought and little rain; poles with high grounding resistance and long-span river-crossing poles; occasions with high operating overvoltage, which require restrictions before entering substations; and areas with serious pollution

III. Conditions of Use

1. The ambient temperature is -40 +40.

2. The altitude should not exceed 2000m.

3. The frequency of power supply is 48 Hz~62 Hz.

4. The maximum wind speed does not exceed 35m/s.

5. Areas with seismic fissure of 7 degrees or less;

6. Lightning arrester is allowed to swing. According to tower shape, suspension mode and pile-sitting mode are considered.
