8.7/15kV Silicone Rubber Elbow Separable Rear Boot
Product Advantage
1. Adopt imported silicone rubber material to produce. Which with excellent insulation performance, heat resistance, cold resistance, dielectric properties, ozone resistance and resistance to atmospheric aging. It can be operated under various kinds working conditions and be widely used in branch cabinets, RMU, enclosure substations and so on.
2. Each batch of raw material passes the mechanical properties and electrical properties index test, which ensures product quality from the source.
3. All finished products 100% pass the factory performance test (power frequency withstand voltage, partial discharge).
4. Import Germany DESMA solid injection production system, combining with dustless and air-conditioned manufacturing workshop with constant temperature and humidity, which ensures the product not affected by external environment and have stable quality.
5. The product is designed according to standard EN50180,EN50181 C type bushing size requirement, and meet the performance requirement of standard IEC60502,GB12706.4.It passed the national authority type test certificate. It is safe and reliable with long time running.
6. Professional engineering installation team and years of installation and operating experience, we can provide on-site installation or installation guidance to ensure installation quality.
7. Excellent inside and outside sheild design, the sheilded separable connectors have stable electric perport without partial discharge and fulfill the fully indulation and sealing of the switchgears.
