Electrical Properties Of Flexible Polypropylene Based Cable Insulation Materials

Polypropylene polypropylene pp also known as polypropene is normally tough and flexible especially when copolymerized with ethylene.

Electrical properties of flexible polypropylene based cable insulation materials.

Having a higher melting temperature than polyethylene polypropylene has been expected to be an insulation material for power cables. Journal of materials science. Electrical properties of cable insulation materials bruce s. But isotactic polypropylene i pp used generally is unsuitable as cable insulation because it shows poor flexibility low breakdown strength due to growing spherulites and so on.

It is similar as polyethylene in electrical properties. Here conductor is insulated with poly vinyl chloride p v c a thermo plastic material. This material is primarily used as an insulation material. Polypropylene pp insulated wire cable.

Dc resistivity and ac breakdown strength of flexible polypropylene trade marked name hifax cable insulation materials have been measured at selected temperatures. This makes it suitable for thin wall insulations. Galaxy is a leading supplier of custom and stock polypropylene pp wires or cables. Rubber insulation is deteriorated shortly but p v c.

Polypropylene has been regarded as a potential recyclable insulation material for hvdc cable which is beneficial to improve the working temperature and transmission capacity of hvdc cables. The ac breakdown data has been analysed in terms of weibull distribution. However the electrical properties of polymeric insulation materials exhibit apparent temperature dependent characteristics. Galaxy can supply pp wires and cables both stock and custom in various awg sizes voltage ratings compounds shielding constructions and conductor counts.

Polypropylene based polymers may have the potential for recyclable thermoplastic cable insulation application because of their high melting temperatures and adjustable mechanical and electrical. Wires with thermo plastic insulation p v c.
