Galaxy can supply pp wires and cables both stock and custom in various awg sizes voltage ratings compounds shielding constructions and conductor counts.
Here conductor is insulated with poly vinyl chloride p v c a thermo plastic material.
Galaxy is a leading supplier of custom and stock polypropylene pp wires or cables.
Rubber insulation is deteriorated shortly but p v c.
Polypropylene pp insulated wire cable.
The results show that hifax cable insulation has a higher ac breakdown strength than epr ethylene propylene rubber and xlpe crosslinked polyethylene.
This type of insulation is not affected by acid alkali ozone humidity or the sun rays.

This material is primarily used as an insulation material.
This makes it suitable for thin wall insulations.
However the electrical properties of polymeric insulation materials exhibit apparent temperature dependent characteristics.
Electrical properties of flexible polypropylene based cable insulation materials article in journal of materials science 41 7 2037 2043 january 2006 with 66 reads how we measure reads.
It is similar as polyethylene in electrical properties.
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.
Polypropylene polypropylene pp also known as polypropene is normally tough and flexible especially when copolymerized with ethylene.
Typically it is harder than polyethylene.
The ac breakdown data has been analysed in terms of weibull distribution.
Paper insulated lead covered cables pilc fundamentals.
Polypropylene based polymers may have the potential for recyclable thermoplastic cable insulation application because of their high melting temperatures and adjustable mechanical and electrical.
Having a higher melting temperature than polyethylene polypropylene has been expected to be an insulation material for power cables.
Temperature influences the generation and migration of charge carriers.
Remains unaffected as it is much harder than rubber.
