Color Customized OEM / ODM Polymeric Composite Surge Arrestors
without Gap
Lightning arrester is a kind of over voltage limiter for protecting
transmission and distribution electrical apparatus (transformer,
switch, capacitor, choke, instrument transformer, generator, motor
and power cable etc) to avoid over voltage damage and it is the
foundation of electric power system insulation.
The main components of metal-oxide arrester, metal-oxide resistance
cards, adopt international advanced technology and manufactured by
good selection and improvement, have the characteristics of
excellent nonlinearity (C-V characteristic), good front-of-wave
response, strong currency capability and excellent anti-ageing
performance, greatly improve the protection capability and
reliability of arrester. Composite-sheath metal-oxide arrester,
adopts the technology of whole-injection moulding and two-head sea
ling, has excellent airproof performance and explosion-proof
capability, dirtiness-resistant, corrosion-resistant, anti-aging,
compact size and low weight, be convenient for insulation and
maintenance.
Porcelain-sheath metal-oxide arrester has excellent structural
characteristics, durable airproof characteristics,
well-proportioned potential distribution and reliable
pressure-releasing device.
