■An overview of the

Direct lightning overvoltage caused by lightning overhead insulated line or easily lead to insulator flashover or breakdown induced over. -voltage, power frequency arc concentrated in insulation breakdown point to cause melting insulation line break. In order to prevent the accident, need the overhead insulated line overvoltage protector installed above the line, its effect is when lightning overhead insulated line, will take a current protector, and cut off power frequency of afterflow, avoid insulator flashover or breakdown, overhead insulated line protection, avoid break accident.

■Product features

Excellent protection feature, through drainage series gap formed between the ring and insulated wire and current limiting element Fei with effect, effectively cutting off stream power frequency, avoid insulated wires in lightning bolt after the accident; Excellent protection feature, through drainage series gap formed between the ring and insulated wire and current limiting element of synergy, effectively cutting off stream power frequency, avoid insulated wires in lightning bolt after the accident; Special mechanical structure (including the load- carrying frame, buffer layer), the unique interface coupling technology and silicone rubber coat a molding process, to ensure that the product can withstand larger mechanical stress, reliable sealing, explosion-proof; Safe and reliable operation, maintenance free. Even with damage due to abnormal situation protection, with series gap isolation effect ?

■Patrol

Suggest thunderstorm period increased number of patrol, found product appearance and drainage in abnormal ring I like: current limiting element coat traces appear breakage, cracks or electric erosion, such as drainage ring deformation, severe electric erosion, and somewhat crooked protector, etc.) please instant replacement.
