Ⅰ. Introduction to 198 Epoxy Bushing
NKS Power presents the 198 Epoxy Bushing, a crucial component for Gas-insulated Ring Main Units (RMU). This bushing is specifically designed to provide robust insulation and support for connections between fixed switch cabinets and cables in inflatable ring network cabinets. It is available in 12kV and 24kV voltage levels with a rated current of 630A to 1250A. The bushing is made from high-quality epoxy resin and features a copper conductive rod with high conductivity.
Ⅱ. Features of 198 Epoxy Bushing
1. High Electrical Performance
It observes superlative standard codes IEC60502.4 and GB/T12706.4. Hence, it can work very well in high-vo environments.
2. Durable Construction
Made of quality epoxy resin material that gives excellent insulation, including mechanical strength.
3. Easy Installation
Quick to assemble, hence easy installation means reduced downtime and maintenance cost.
4. Compatibility
It can be used together with compatible separable cable connectors to attain full shielding and sealing.
