Product Description

Overview

H.V. Surge Arresters are used to protect transformers and other equipments in station and distribution systems against the damage by atmospheric (especially lightning effects) and operational conditions.Metal oxides surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.


Normal operating conditions:

1.Ambient temperature :-40ºC~+40ºC;

2.Radiation of sunlight:Note:The influence of the maximum sun exposure (1.1 KW / square meter) has been considered by the method of preheating the sample in the type test.If there is other heat source near the arrester, the use of the arrester needs to be negotiated by both parties..

3.Altitude:≤2000m;

4.Frequency:50Hz or 60Hz;

5.The power frequency voltage applied between the terminals of the arrester for a long time shall not exceed the continuous operating voltage of the arrester;

6.Earthquake intensity below 7 degrees;


Features:

1. Small size, light weight, collision resistance, no loss of transportation, flexible installation, especially suitable for use in switch cabinets;

2. Special structure, integral molding, no air gap, good sealing performance, moisture proof and explosion proof;

3. Large creepage distance, good water absorption , strong pollution resistance, stable performance, and the operation and maintenance are reduced;

4. Uniquely formulated zinc oxide resistors, high capacity, low leakage;

5. The actual DC reference voltage, square wave flow capacity and high current withstand capability are higher than the national standard.
