Explosion-proof surge arrester YH10W5-18/49.5

varistorpolymerAC

1. The Core column applied winding structure, Polymer Housed core pillar molded on the core column, with almost no internal air gap, and outstanding sealing performance Simple in structure, small in size and light in weight. 2. Polymer Housed with silicone rubber, explosion-proof ZnO varistor as the core component is large in flow capacity. 3. International standard IEC 60099-4 and ANSI 62.22, and with high reliability. With fully insulated tops, the product can be applied to the complete cabinet installation, which can reduce the designing size of cabinet. 4. Products with detachment device can provide signals for quitting operation when failure occurs, avoiding arrester explosion, and it is maintenance-free. 5. Polymer housed products with a six CTI level, creepage distance meets the requirements of IV level in heavy pollution areas. 1.The ambient temperature is not high than +40 celsius and not lower than -40 celsius. 2.The altitude above sea level do not exceed 1000-2000m.(Altiplano area should be indicated when order.) 3.The frequency in AC system is 50Hz or 60Hz. 4.Power frequency voltage which has been bearing on arrester for a long time do not exceed continuous operating voltage. 5.Max. wind speed do not exceed 35m/s. 6.Apply to the area where earthquake intensity is not exceed 8 degree. 7.The filthy area should be indicated before. 1,All the substations 2,All the electrified railways 3,All the distribution lines 4,Electric equipments 1.The low weight facilitates installation and permits erection in limited spaces and at almost all angles. 2.No continuous current and low current impulse residual voltage.
