Cable manufacturers making automotive cables in India are using insulation materials providing extreme reliability and durability under operating conditions. In this post, you will learn about these insulation materials, their structure and properties in brief.
Thermoplastics are used as insulation material by auto cable manufacturers as these materials are known for their ability to melt and remold repeatedly. This is possible due to their structure that is made of molecule chains that get separate once exposed to heat. There are different types of thermoplastics available in the market- PVC, polyurethane, TFE, FEP, and polypropylene.
- Thermoplastic elastomers
Thermoplastic elastomers include a mix of polymers, usually a plastic and rubber. It can be molded, extruded, recycled just like plastic without losing the flexibility and stretch of rubber. Thermoplastic elastomers are applied to the applications where conventional elastomers are unable to provide basic range of physical properties. You can find them in automotive applications and household appliances.
However, there are limitations of thermoplastic elastomers – poor chemical resistance, unable to resist heat, low thermal stability, and expensive insulation option.
- Elastomers or cross linked plastics
Polyethylene or XLPE type of insulation is formed via both heat and high pressure. Wires with XLPE insulation are able to transmit large currents and high voltages. Automotive cable manufacturers use automotive wire (GXL) XLPE wire. The common use of these wires is to supply medium to high voltage to applications.
What is the selection criteria for materials?
There are certain factors that manufacturers count on –
- Service temperature
- Electrical values
- Mechanical stability under load
- Flexibility or hardness
- Wear resistance
- Resistance to oil, brake fluid, fuels, alkalis, acids, and organic agents
- Flame retardant
- Halogen free
- Low halogen
Cables and wires made with XLPE insulation have following properties-
- Temperature resistance
- Solvent resistant
- Chemical resistance
- Bending resistance
- Abrasion resistance
Cable manufacturers are not only making automotive cables, but also producing building wire, power cables, direct burial cables, submersible cables, control cables, etc.
How to choose one reliable manufacturer and supplier to source cables?
It’s easy yet time taking job!
- You need to sit and patiently find a few names of suppliers online or via business directory.
- Find out if they are having social page where you can read real unpaid reviews about their services and products.
- Shortlist the names
- Compare the pricing chart and quality offered by them.
These are the basic rules to follow while looking for a reliable vendor to source cables and wires. There are few suppliers that claim their products to be the best in market at competent price but when you really roam in the market and make a deep research report, you will find these claims useless. Be wise and take decision like a pro.
If you live in India, choose the best suitable supplier of automotive cables in India. Local vendor can provide you unmatched quality product at reasonable price.
