20kV Inner Cone Connect Cabinet Busbar Connector
Range of Application
l Apply to switch connect cabinet for voltage of 6/10kV,8.7/10kV,8.7/15kV, rated current of 630A with function of fulfilling side extension of neighboring switch unit, insulation protection and electrical transmission.
Product Description
l Inner cone connect cabinet busbar, adopted silicone rubber material of international famous brand to produce which with excellent insulation performance, heat resistance, cold resistance, dielectric properties, resistance to ozone and atmospheric aging properties, and can be operated under any working conditions.
l Each batch of raw material have been passed the mechanical properties and electrical properties index testing, which ensures product quality from source.
l All finished products 100% takes the factory performance test.
l Import DESMA liquid injection production system, with dustless and air-conditioned manufacturing shop, and constant temperature and humidity all year round, which ensures the product not affected by external environment and the quality stability of product.
l Complies with the inner cone I type bushing size requirement of EN50180,EN50181 standard and the performance requirement of IEC60502,GB12706.4 standard, safe and reliable with long period operation.
l With professional engineering installing team, and years of installation and operating experience, providing the field installation and guide installation, we can make sure the finished product installation quality.
Technical Feature
lSide Connect Cabinet Busbar system, adopt new type semicrystalline polymer to produce, with big toughness, excellent electricity, heat resistance, chemical resistance and crack resistance
Excellent internal cone type structure design, space of switch bushing can be less than 100mm.
lnner cone combined cabinet busbar, adopted copper bar to process, silvering product surface, using non-magnetic and constant force spring to fixed, which ensures the good cooperate of hardware.
Circular connection of busbar connection hardware and bushing hardware, big contact area, strong flow capacity.
Inside and outside screened design of product, screened resistance lower than 5kΩ,which ensures the safety of product operating and operator, as well as achieve the performance of all insulation, whole sealing, protection, maintenance-free, dust-resistant and so on.
