In large electrical distribution systems, there are various products used for safeguarding the electrical flow and preventing the occurrence of faults. Whether it is a building, a facility, a factory, a warehouse or a distribution substation, there is one common equipment that is used- switch gears. Switch gears are an assembly of various components that control, protect and isolate an electrical system. It consists of circuit breakers, fuses, relays, busbars, and metering devices. Several insulation components are critical in various switchgear operations. For instance, a spout is used to connect a busbar terminal to a circuit breaker. Or, a bushing provides a safe passage for current through the conductor. Switch gear components manufacturers like Prominent Power Products Pvt. Ltd. use epoxy to make the bushing, spout and insulators. Its properties are ideal for insulation and maintaining the safety of the current flow.
Properties of Epoxy
The main reason why epoxy is preferred by switch gear components manufacturers for insulating their parts is the inherent properties and treatments done by the manufacturers. Here are the key properties to know about Epoxy material:
- Dielectric Strength
Dielectric strength refers to the capacity to withstand the maximum voltage per unit thickness before the current flows through it. For Epoxy resins, this value is quite high. Therefore, it can handle high voltage without damage or conduct electricity through itself.
- Resists Overarcing
Arcing of current through the insulating material can erode or decompose it. The arc resistance of Epoxy insulators is excellent, ensuring the equipment is safe from damage caused by arcing of current.
- Temperature Endurance
The chemical formulation of Epoxy is such that it develops high thermal resistance, that is, it can resist the heat developed in the conductors. The additives, flame retardant chemicals and curing agents are used by switch gear components manufacturers in making the Epoxy parts sufficiently thermally resistant.
- Mechanical Resilience
The switchgear devices not only face high electrical stress but also mechanical stress as dense metal parts are involved. Hence, a material like Epoxy is ideal to handle various loads and vibrations in the switchgear assembly. Warping and distortion are avoided with its robust mechanical strength.
- Moldability
Epoxy resins can be easily moulded and given accurate shapes of various protective designs of the switchgear. For instance, the corrugated bushing with consistent patterns is ensured by the precision engineering method, and molten materials of epoxy resins form that shape with perfection.
