Y10WZ-100/260,Y10W-108/280Zinc Oxide Arrester Porcelain Insulation

Product Introduction

The Y10WZ-108/280 Porcelain Jacket Arrester is an arrester with good protective properties. Using the good nonlinear volt-ampere characteristics of zinc oxide, the current flowing through the arrester is extremely small (microamp or milliamp level) under normal working voltage; when overvoltage acts, the resistance drops sharply, discharging the energy of the overvoltage and achieving a protective effect. The difference between this arrester and the traditional arrester is that it has no discharge gap and uses the nonlinear characteristics of zinc oxide to play the role of leakage and interruption.

Y10WZ-108/280 Porcelain JAcket Arrester is the current international advanced overvoltage protector. Because its core element resistor is made of zinc oxide and various metal oxides, compared with the traditional silicon carbide arrester, the volt-ampere characteristics of the resistor are greatly improved, and the current capacity of the resistor is improved, thereby improving the characteristics of the arrester. fundamental change.

When the arrester is under normal operating voltage, the current flowing through the arrester is only microampere. When subjected to overvoltage, the excellent nonlinear volt-ampere characteristics of the arrester play a role, and the current flowing through the arrester instantly increases to thousands of amperes. In the conduction state, the overvoltage energy is released, thereby effectively limiting the damage of the overvoltage to the power transmission and transformation equipment.

Model Description

Working Environment：

1. The ambient temperature is not higher than +40 °C. Not lower than -40°C;
2. Altitude: no more than 2000m;
3. Power frequency: 50/60Hz;
4. Earthquake intensity: 7 degrees and below;
5. Maximum wind speed: 35 m/s;

For long-term use in the following abnormal conditions, the arrester needs to be specially made and should be specified when ordering:

• The temperature or altitude exceeds the standard (plateau, tropical, frigid, fully enclosed cabinet, close to electric furnace, etc.);
• There are serious moisture or corrosive gas impurities in the environment (water, salt fields, chemical plants, etc.);
• Strong ultraviolet radiation (plateau, strong sunshine area, etc.);
• Extraordinarily polluted areas (mine face, construction site face, etc.).
