Difference between Cable Insulation Materials - (PVC, PE and PVC)

Power cables can transmit and distribute electrical energy. The power cables have broad use in urban underground power grids, power station diversion lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas.

Because of the increasing usage of cables, power cables of various voltage levels and various insulations from 1-500KV and above have appeared. At present, the insulation materials used in cable production are PE, PVC, and XLPE. 

ZMS Cable Manufacturing Company is a professional cable manufacturing company that produces a variety of environmentally friendly PVC and XLPE insulated high school and low voltage cables and cables.

All of our cable products are high-quality cables that have been rationed through repeated experiments and have also passed international environmental quality certifications, such as IEC, BS, GB, etc. If you need it, the staff of ZMS Cable can also provide you with certificates of relevant standards.

What is The Difference between Them?

PVC: Polyvinyl chloride, a polymer made by free polymerization of vinyl chloride monomer under specific conditions.

Characteristics: Stable, acid-resistant, alkali-resistant, corrosion-resistant, and aging-resistant

Applications: construction materials, everyday products, pipes and tubes, wires and cables, sealing materials

Materials: soft and hard

Soft can manufacture packaging materials, agricultural films, etc. We often use it as the insulation layer of wires and cables, such as PVC-insulated power cables.

The rigid material can make pipes and sheets.

PVC has superior flame retardant properties. That's why it is possible to use it in the manufacture of flame-retardant and fire-resistant cables.

ZMS Cable Manufacturing can provide customers with flexible, rigid PVC insulated power cables, and we can also customize cables productions to meet your needs.

 

PE: Polyethylene, a thermoplastic resin made by polymerization of ethylene.

PE is non-toxic and harmless, low temperature resistant, acid and alkali resistant, excellent electrical insulation properties, low loss, and high electrical strength.

PE acts as an insulating material for high-voltage wires and cables.

 

XLPE: Cross-linked Polyethylene, is an advanced form of polyethylene material after the change. After improvement, it has a substantial improvement in physical properties and chemical properties compared with PE.

Features: lightweight, good heat resistance, corrosion resistance, relatively high insulation resistance.

 

XLPE Insulation Has The Following Advantages Compared to Thermoplastic Polyethylene (PE):

1. Increased XLPE heat deformation resistance, improved mechanical properties at high temperatures, improved resistance to environmental stress cracking, and heat aging.

2. XLPE (cross-linked polyethylene), chemical stability, and solvent resistance are stronger, long-term working temperature up to 125 ℃ and 150 ℃. The short-circuit resistance is better, and the short-term withstand temperature can reach 250℃.

3. Superior mechanical, water, and radiation resistance. 

ZMS Cable Manufacturing companies specializing in developing insulated cables for 30 years. We can customize many types of PVC, PE, XLPE insulated medium, and high voltage power cables.

The Difference of Cable Insulation Materials PVC, PE, XLPE

PVC: It has good physical and mechanical properties, good processing properties, low cost, and high sales price. However, it contains halogen and has an amount of sheathing. It is not resistant to high temperatures, has weak loading capacity, and emits harmful gases when burned.  

PE: excellent electrical properties, has all the advantages of PVC.

XLPE: Electrical properties are almost as good as PE, long-term working temperature is relatively higher than PE, mechanical properties are better than PE, and aging resistance is better.

It is a new type of environmentally friendly product with high-temperature resistance and good environmental resistance thermosetting plastic. It always applies in electronic lines and places with high requirements for ambient tolerance.

 

The Difference Between XLPO and XLPE

XLPO (cross-linked polyolefin): EVA, low smoke halogen-free class, irradiated cross-linked or vulcanized rubber-like cross-linked olefin polymer. A general term for a group of thermoplastic resins obtained by the individual polymerization or co-polymerization of ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, and other alpha-olefins, as well as certain cyclic olefins.

XLPE (cross-linked polyethylene): XLPE, cross-linked polyethylene, silane cross-linked or chemically cross-linked, is a thermoplastic resin made from ethylene by polymerization. In industry, it also includes copolymers of ethylene with small amounts of alpha-olefins.
