Introduction to inner braiding and outer braiding of Automotive Wiring Harness Protection Sleeve

When some customers ask about related issues about Automotive Wiring Harness Protection Sleeve, they have this question: Which one has better voltage resistance, the inner Automotive Wiring Harness Protection Sleeve or the outer Automotive Wiring Harness Protection Sleeve? Below is a brief explanation.

Automotive Wiring Harness Protection Sleeve are also called enhanced Braided Sleeve, and enhanced Braided Sleeve can be divided into two types: inner Automotive Wiring Harness Protection Sleeve and outer Automotive Wiring Harness Protection Sleeve. Depending on the purpose, the materials are also different. Generally, low-pressure ones are usually fiber braided, and high-pressure ones are usually steel wire braided. The more layers, the greater the pressure.
The so-called outer Automotive Wiring Harness Protection Sleeve is currently commonly used as wrapping cloth, which can enhance the pressure of the pipeline, wear resistance, corrosion resistance, etc. Similarly, the more layers, the greater the pressure.
But for hydraulic pipes, which are internal car wiring harness protective covers, they mainly rely on the internal reinforcement layer to resist pressure, and the outer wrapping cloth will not play much role. Most of the common cloth-wrapped hydraulic pipes on the market are made in China. Due to the backward technology, layers of cloth are still used. Other common cloth-wrapped tubes include steam Braided Sleeve used in the steam field for safety.
Therefore, the burst pressure has nothing to do with the inside and outside. It depends on the manufacturer's product instructions. Under normal circumstances, the burst pressure of domestic pipelines is about 2 times the working pressure, and of course some of them can reach 3-4 times. Foreign ones should be around 4 times. If it is applied in the high-voltage field, this aspect must be paid attention to.
