The Importance of Wire Harness Protection

As global car sales continue to rise, the market share of electric vehicles is also increasing yearly, undoubtedly playing a crucial role in our lives. Automotive wire harnesses are responsible for connecting various wires in an organized manner to ensure the proper functioning of vehicles. However, automobiles must withstand extreme conditions such as temperature variations, vibrations, and voltage fluctuations. For the considerations of safety and durability in usage, the insulation sleeves that protect these critical wires have become an indispensable assistant. Good Gi, offer a range of heat-resistant, high-voltage-resistant, and durable insulation tubing that provides comprehensive protection for automotive wire harnesses, ensuring that the wires can operate reliably under harsh conditions.

Corrugated Tubing: Superior Flexibility and Protection

Made from various plastic materials, including Polyethylene, Polyamide or Nylon, and Polypropylene. (Further reading: What is convoluted tubing?) Among other plastic materials, Polypropylene convoluted tubing is commonly selected for engine surroundings due to its high melting point, excellent flame resistance, and low thermal conductivity. With the high temperatures around the engine, Polypropylene convoluted tubing ensures the protection of surrounding components, prevents fire hazards, and complies with FMVSS 302. Additionally, Polypropylene convoluted tubing has a higher hardness, protecting wires against vibrations and abrasion during vehicle operation.

Heat Shrink Tubing: Effective Enclosure and Protection

Heat shrink tubing has a unique characteristic where its diameter shrinks when subjected to heat, allowing it to encapsulate wires or cable bundles regardless of their shape tightly. It provides insulation, flame resistance, and weather resistance for enhanced protection. Compliant with UL 224, YDPU2, and CUL YDPU8 certification due to the requirement for heat application during installation, it is typically not widely used for large-scale applications. Typical applications include wire terminations or end caps for other tubing. For sealing purposes, adhesive-lined heat shrink tubing can be chosen, as it effectively seals out external factors such as moisture or dust. It has wide applications in waterproofing, leak prevention, and corrosion protection for repairs.

Fiberglass Sleeving: High-Temperature Resistance and Protection

Fiberglass sleeving is a representative material among high-temperature insulation tubing, capable of withstanding temperatures up to 500 ℃. Conforms to flame test UZIQ2 and UZFT2 insulation test in UL 1441. It possesses flame retardant and self-extinguishing properties, making it highly suitable for applications in high-temperature environments, particularly within automotive interiors. It effectively protects against hazards and reduces the risk of incidents. Additionally, fiberglass sleeving offers flexibility, allowing for easier installation. Apart from the automotive sector, it finds widespread applications in aerospace, electronics, industrial machinery, and other industries. It plays a crucial role in these fields.
