★ Components Of A Wire Harness
1
Wires and Cables
Conductors —typically copper or aluminum— that transmit electrical power or signals.
2
Insulation
A layer of material used to protect the wires and prevent shorts, moisture, and environmental damage.
3
Connectors
Interface devices that securely connect wires to other wires or components.
4
Protective Sheathing
Additional coverings such as plastic tubing, fabric wrap, or heat shrink to shield wires from abrasion, heat, and moisture.
5
Terminals
Points in the harness where wires connect to other components using metal end crimping or soldering.
6
Mounting Hardware
Clips, ties, or fasteners used to secure the wire harness in place.
★ Cable Harness Assembly Material Types
We have gained adequate expertise in the design and manufacturing of custom cable harness assemblies in a cost-effective manner; but high-performance cable projects. Our solutions include the prototyping, design, development, and management of custom cable assembly for both low volume/high mix to high volume/low mix production capacities. Following are the different material types of electrical cable:
1. PVC (Polyvinyl chloride)
PVC is a synthetic plastic material that is commonly used in wire harnesses due to its low cost, durability, and resistance to fire, chemicals, and UV radiation. It is also flexible and easy to work with, making it a popular choice for a variety of applications.
2. Vinyl
Vinyl is another synthetic plastic material that is like PVC in many ways. It is also relatively low cost and durable, and it is resistant to moisture, chemicals, and UV radiation. However, vinyl is not as flexible as PVC, which can make it more challenging to work in some cases.
3. Thermoplastic elastomer (TPE)
TPE is a rubber-like material that combines the properties of rubber and plastic. It is known for its flexibility, resilience, and resistance to temperature, chemicals, and UV radiation. TPE is also easy to process and can be used in a wide range of applications.
4. Polyurethane (PU)
PU is a synthetic material that is known for its high strength, toughness, and resistance to abrasion and impact. It is also flexible and resistant to chemicals and UV radiation. PU is often used in harsh environments where wire harnesses need to withstand extreme conditions.
5. Polyethylene (PE)
PE is a thermoplastic material that is known for its low cost, flexibility, and resistance to moisture, chemicals, and UV radiation. It is also lightweight and easy to process, making it a popular choice for a variety of wire harness applications. However, PE is not as strong as some other materials and may not be suitable for all applications.
