Introduction To The Selection Method Of Pre-insulated Bushing

pre insulated sleeve is widely used in various wiring harness protection solutions due to its excellent high temperature resistance and insulation performance. pre insulated junction sleeve is made of glass fiber filaments woven into a tube and then immersed in silicone resin and treated at high temperature, so its pressure resistance and temperature resistance levels are very high and can meet the needs of different industries. But how to choose insulated joint sleeve to get a satisfactory product?

1. Determine the performance parameters of the product
Determining the performance parameters of the glass fiber casing is the first step in the selection, which includes the color and size of the casing to be purchased, and the pressure resistance level of the glass fiber casing and the temperature requirements of the use scenario. And determine the type of glass fiber casing, and choose to buy silicone rubber glass fiber tube and silicone resin glass fiber tube according to actual needs.
2. Fully understand the quality of the product
There are many manufacturers of glass fiber casing on the market, and the quality of the products is also uneven. Consumers can simply judge the quality of glass fiber casing by touching and smelling when purchasing products. When touching, you need to feel the texture and fineness of the casing and the uniformity of the particles, and you need to pinch the product to observe its hardness. If the hardness is low and the casing can be kneaded and deformed at will, it is unqualified. In addition, pay attention to the smell of the product when smelling. If there is a pungent smell, it means that the quality is poor.
3. Choose products from well-known large companies as much as possible
Well-known large-scale fiberglass casing manufacturers generally have a relatively complete product inspection process. Facing fiberglass casing products of different brands on the market, you should insist on shopping around. Only when you make sure that the samples are completely qualified can you order to ensure quality. And because most of the products produced by well-known companies are industry-leading fiberglass casings, when ordering, try to choose products from well-known brands. Don't lose the big picture because of a temporary desire for cheapness. After all, you get what you pay for. High-quality fiberglass casing products can prevent quality problems such as glass fiber breakage when in use.
In short, the selection of fiberglass casing mainly refers to the above three aspects, including determining the parameters of the product, understanding the quality of the product, and choosing products from well-known companies.
