AC transmission line arresters composite jacket is an excellent over-voltage protection devices are widely used to protect transmission lines, especially in the frequent lightning activity, soil resistivity greater difficulty mountain patrol line, can greatly reduce the transmission line lightning damage accident. Line arrester with series gap can be divided into two groups with and without gaps, with a series of pure air gap arrester can be divided into two kinds of gaps and insulator gap.
The product has the following characteristics: ⑴ small size, light weight, easy to install suspension; ⑵ using reliable sealing structure design, good sealing performance, moisture-proof, maintenance-free; ⑶ external insulation using high-quality, imported a two-component liquid silicone rubber injection molding process, hydrophobicity, good stain resistance, resistance to corrosion, aging resistance, high tear strength, resistance to impact, transport without damage; ⑷ line arrester with series gap, because the gap isolation resistor very light load operation, operation and maintenance workload minimal; ⑸ good heat dissipation performance, prevent aging resistors; ⑹ high mechanical strength; ⑺ can withstand multiple lightning strikes, long working life; ⑻ unique design to counter the insulation provided for easy installation.
