HY1.5W-0.28/1.3 low voltage arrester Product Overview
Arrester is the power systems of various types of electrical equipment (transformers, reactors, capacitors, generators, the PT, CT, circuit breakers, contactors, etc.) the basis for insulation coordination, arrester protection performance of all electrical equipment to determine the power system both inside and outside insulation index ( The short-time power frequency withstand voltage, lightning impulse withstand voltage, and operation of the impulse withstand voltage)
Metal oxide surge arresters, commonly known as zinc oxide arrester is a new generation of the 1980s by the United States, Japan and other countries in the international popularization of arrester is often effect the most advanced products in the arrester. China since the mid-1980s to the introduction of the technology, through years of practice to digest arrester performance of professional arrester plant exchanges with the most advanced products in the United States, Japan, Western Europe and other countries the gap between comparable straight is reached all the requirements of GB The products also meet the requirements of the International IC standard.

HY1.5W-0.28/1.3 low-voltage surge arrester model Description:
HY: composite jacket insulation, zinc oxide varistor; 1.5: Nominal discharge current (KA); W: no gap; Z: type of power station: 0.28: the arrester Rated voltage (KV); 1.3: Nominal discharge current maximum residual pressure (KV)

The basic principles of HY1.5W-0.28/1.3 low-voltage surge arrester
HY1.5W-0.28/1.3 low-voltage surge arresters. As its core component of zinc oxide varistors, compared with traditional silicon carbide arrester, superior volt-ampere characteristic, high flow capacity, resulting in fundamental changes in the arrester characteristics.
Under the normal operating voltage, the flow through the arrester current is only microampere level, in the insulating state; when subjected to the voltage, due to the excellent nonlinear zinc oxide varistors, the current flowing through the arrester and instantly thousands of amperes, surge arresters in a conduction state, the release of over-voltage energy, the arrester residual voltage over-voltage amplitude is limited within the allowable value, thereby effectively limiting the damage of over-voltage transmission and distribution equipment.

HY1.5W-0.28/1.3 low-voltage surge arresters conditions of use
An ambient temperature not higher than +40 ° C, not less than -40 ℃;
2 altitude over 2000m (more than 2000m when ordering, the choice of the plateau);
3 AC frequency 50Hz or 60Hz;
Four long-term power frequency voltage does not exceed the arrester continuous operating voltage applied between the arrester terminals;
5, the maximum wind speed does not exceed 35m / s;
6 seismic intensity of 7 degrees and the following areas.


These are HY1.5W-0.28/1.3 low-voltage surge arrester details, if you HY1.5W-0.28/1.3 low-voltage surge arrester of the price, make, model, parameters, pictures have any questions, please contact us for HY1.5W-0.28/1.3 low-voltage surge arrester the latest information
