100mm New Energy Vehicle Wiring Harness

Corrugated Pipe New Energy Vehicle Wiring Harness 100mm High Voltage Car Air Purifier Wires

Product introduction

The automotive wiring harness also requires very strict materials:

Including its electrical performance, material emission, temperature resistance, etc., it is higher than the general wiring harness requirements, especially when it comes to safety: the wiring harness for important components such as the direction control system and brakes is more stringent.

Wiring Harnesses for Automobiles that Connect You to the Cars .Automobiles are operated by a variety of electric controls such as being able to start the engine by pushing one button. Along with the increase in functions for automobiles, the number of electric devices installed is also increasing. The wiring harnesses play a role in connecting those devices and delivering electricity and signals through the entire car. The functions are similar to the blood vessels and nerves of a human body.

AWG(AMERICAN WIRE GANGE) specification

Selection of materials for new energy high-voltage wires:

TPE

The types of TPE are: styrenes, olefins, dienes, vinyl chlorides, polyesters, esters, amides, organic fluorines, silicones and vinyls (TPS, TPU, TPO, TPV, etc.) ).

Most of the current use refers to SEBS-based elastomers. TPE material used in charging gun cable

Advantages: The processing technology is simple, the density is small, the price is moderate, the overall cable is very soft, and can meet the requirements of the existing standards.

Disadvantages: most contain unsaturated bonds, poor temperature stability; low oil resistance, especially gasoline; poor weather resistance, poor thermal stability of materials for long-term use, mechanical properties of materials drop a lot under high temperature conditions,

There is a high risk of cracking when used outdoors; intolerant of dirt and sticky hands.

Working temperature: cold resistance -50 degrees; temperature resistance within 120 degrees.

TPU

TPU, that is, thermoplastic polyurethane elastomer, molecular structure is divided into polyester type and polyether type, composed of rigid blocks and flexible segments, injection molding accounts for more than 40% in the processing process, extrusion molding is about 35% ; The spring extension length can reach 2-6 times the original spring length.

The polyurethane sheath material of the charging pile cable is made of TPU resin, which is added with environmentally friendly or halogen-free flame retardants, antioxidants and other additives after mixing, plasticizing and granulating. It is flexible and resistant to rolling. Withstand voltage, high temperature pressure, aging resistance, acid and alkali resistance, salt spray resistance, waterproof and other characteristics.

Advantages: It has excellent high tension, high tension, toughness and aging resistance, environmentally friendly materials.

Disadvantages: At present, domestic processing is difficult, there are fewer raw material enterprises, and the cost is higher.

Working temperature: cold resistance -40 degrees; temperature resistance within 150 degrees.

Polyvinyl chloride elastomer

PVC polyvinyl chloride cable, based on polyvinyl chloride, can be adjusted by adding different amounts of plasticizers to adjust its softness and reduce its "glass transition" temperature, thereby having good flexibility and increasing plasticity. Make it easy to process.

After cross-linking, the chain segments form a network structure, and the elastic expansion and contraction length can reach 2-4 times of the original spring length.

Advantages: flame retardant and insulation, acid resistance, oil resistance, easy processing and modification, and cheap.

Disadvantages: There will be black smoke and HCl gas when burning.

Working temperature: cold resistance -40 degrees; temperature resistance within 105 degrees (according to customer requirements).

Silicone Rubber

The AGR silicone rubber cable processed with silicone material has good elasticity. The suitable temperature range is -60 ℃ -200 ℃ Voltage: 300 / 500V Conductor material: The process principle is similar to rubber, and it is processed through mixing, high-pressure molding and other processes.

Advantages: heat resistance, cold resistance and weather resistance, waterproof, good flexibility, easy to install.

Disadvantages: the price is more expensive.

Working temperature: cold resistance -40 degrees; temperature resistance within 200 degrees.

XLPE

XLPE cross-linked polyethylene is a physical or chemical method that changes the molecular structure of XLPE insulating materials from a linear molecular structure to a network-like linear structure. PE is the basic resin, and silane is the bridge bond material.

Advantages: high cross-linking, good flexibility, good insulation, light structure, easy installation and cheap.

Disadvantages: poor heat resistance, color difference between batches is difficult to control.

Working temperature: cold resistance -50 degrees; temperature resistance within 100 degrees.
