Why Silicone Coated Fiberglass Sleeves Have Joints

Hits: 599 img

Silicone coated glass fiber sleeve is woven into a tube by glass fiber yarn, and then coated with silicone insulating oil for high temperature treatment. It is characterized by self extinguishing, wear resistance, tear resistance, good compatibility with similar impregnating varnish, good mechanical properties, softness, and insulation. It is often used for internal wiring harness of electronics, electrical appliances and automobiles, H and C motors, transformers, inverters, inductors, reactors, generators, heating equipment, lighting, etc. In addition, Shunbo silicone coated fiberglass casing has obtained the CUL, REACH and ROHS certificates required by the whole industry, and the joint problems that often occur in the industry do not exist.

The joint problem usually occurs on the silicone coated fiberglass sleeve. Some 4-5 joints are few, but some 10-15 joints are terrible. What causes more joints?

1. When the high-speed braiding machine weaves the germ tube, it causes the germ tube to be worn or contaminated with engine oil, resulting in a section of glass fiber casing with poor quality that needs to be cut off and reconnected to the glass fiber casing with good quality;

2. The glass fiber casing is subjected to high temperature treatment when being coated with silicone resin. Sometimes the temperature is too high or too low, and the quality is seriously reduced. It needs to be cut off and connected to a good casing;

3. When packaging, there will be less than the standard packaging quantity of a roll, and the casing will also be connected to form a complete roll, leading to the appearance of joints;

4. During QC inspection, the defective pipes will also be cut off and connected with good silicone coated fiberglass sleeves;
