When it comes to car safety, everyone's attention is generally focused on collision avoidance and active safety. However, with the increasing number of electrical appliances in the car, the accompanying circuits are also becoming more and more complex, but the hidden dangers have not been noticed by most people. So today Sunbow will tell you about this very inconspicuous but very important part: harness protection.

       The car wiring harness is the main body of the car circuit network, connecting the electrical and electronic components of the car and making them function. Without the wiring harness, there is no car circuit. For example, if a car is compared to the human body, it can be said that the computer is equivalent to the human brain, the sensor is equivalent to the human sensory organ, the executive element is equivalent to the motor organ, then the wiring harness is the nerve and blood vessel. This shows how important the wiring harness is.

       What are the protective measures for automobile wiring harness wires?

       Corrugated pipes, PVC pipes, PET winding pipes, woven cloths, sponges, electrical tapes are generally used for protection of automobile wiring harness wires, and cable ties and straps are used for fixing. It mainly plays the role of fixing, wear-resistant, flame-retardant, insulating, anti-corrosion, anti-interference, reducing noise and beautifying the appearance of vehicle cables.

       The main protection method: automotive wiring harness bellows

       Although the wiring harness bellows are very similar in appearance and appearance, there are indeed many kinds of materials. There are polypropylene (PP), nylon (PA), polypropylene modified (PPMOD), etc. Its main features are good wear resistance and high temperature resistance, even the most common bellows can withstand high temperature up to 100 ° C, and The flame retardancy is excellent, and the wire harness corrugated tube itself has good flexibility and good bending resistance. Bellows are most common in nacelles and in front and rear protective structures. Nylon flame retardant corrugated pipe is the most widely used in the field of automotive wiring harness. Nylon corrugated pipe is made of high-quality nylon material with excellent physical and chemical electrical properties. , automation control and other industries.

      Nylon bellows material: nylon PA6; normal working temperature: -40℃-+130℃ can be -150℃ for a short time; flame retardant grade: V0 (UL94), according to FMVSS 302 requirements, burning speed <100mm/min; structure: internal And the appearance is wavy; Features: good flexibility, anti-torsion, good bending performance, can withstand heavier loads. Acid-resistant, lubricating oil, coolant and other surfaces are glossy and friction-resistant; environmental standards: ROHS, halogen-free, phosphorus-free; nylon bellows conventional colors: dark gray, black, orange.

      Nylon corrugated pipes have environmental protection ROSH, airtight and waterproof IP68, CSA, UL EN50262 and other international standard inspection certifications; this product can be widely used in harsh high-strength alkaline environments or in poor outdoor environments.

       Sunbow Shenzhen Factory was established in October 2003. It develops and manufactures fiberglass sleeves, PVC hoses, silicone hoses, heat shrinkable tubes, Teflon tubes, braided mesh tubes, corrugated tubes and other insulating sleeves.

Since its establishment in 2008, Sunbow Insulation Materials has gone through a 12-year pursuit of high quality. Benchmarking and catching up with international brands has always been Sunbow's goal. At present, Sunbow has become a long-term supplier to more than 20 of the world's top 500. , and more than 1,000 companies have purchased Sunbow's series of casings all year round, and have maintained a record of no quality accidents and incidents for 12 years.
