1. Brief Introduction
AC transmission line arrester is a performance of over-voltage protection devices, widely used to protect transmission lines, especially in the frequent lightning activity, soil resistivity, inspection difficult mountain, can greatly reduce the transmission line lightning damagethe accident rate.
Line arrester points with two types of series gap and gapless, the gap arrester with series is divided into the pure air gap and the insulator gap.
Characteristics of the products
1. Small size, light weight, easy hanging installation
2. Reliable sealing structure, good sealing performance, moisture-proof, explosion-proof, maintenance-free;
3. External insulation using high-quality, imported two-component liquid silicone rubber injection molding process at the water repellency and stain resistance performance, electrical corrosion resistance, aging resistance, high tear strength, crashworthiness, transportation without damage;
4. With Series Gap line surge arrester, gap isolation, varistors run load very light, the workload of operation and maintenance is extremely small;
5. Lightning arrester heat dissipation potential is strong, resistors aging resistance performance is good;
6. Strong mechanical strength
7. Can withstand multiple lightning strikes, long working life
8. The unique insulation structure design to counter installation convenience
