‍High pressure heat shrinkable tube is a kind of tube which is used to shrink and wrap the busbar after heating with fashion set on the busbar. It has the functions of electric insulation, rust prevention, corrosion prevention, reducing phase spacing and so on. It is mainly used in the special place of high voltage transformer. Consumers are often overwhelmed by the dazzling high pressure heat shrinkable tube products on the market when purchasing high pressure heat shrinkable tube, so how to buy the high pressure heat shrinkable tube that meets their needs?‍

1. Select the product according to the required specifications

In terms of materials, the high pressure heat shrinkable tubes on the market mainly include PE and irradiated cross-linked polyolefin materials. Generally speaking, the high pressure heat shrinkable tubes made of polyolefin high-tech materials have better performance: it has stronger stability, faster shrinkage rate, and better wear and impact resistance. In terms of size, usually choose high pressure heat shrink tube products with the same diameter or slightly larger diameter with the bushsleeve.

2. Select according to the required performance

The voltage class of high voltage heat shrink tube is usually greater than 10KV, the greater the value, the greater the voltage strength it can withstand. Generally, low-voltage heat-shrinkable tubes are often used for those with no special requirements for voltage, and can also be replaced by high-voltage heat-shrinkable tubes. Where high-voltage heat-shrinkable tubes are used, low-voltage heat-shrinkable tubes must not be replaced, otherwise major safety risks will be buried.

3. Choose and buy according to manufacturer and brand

It is also a headache for consumers to know which products and brands of high-pressure heat-shrinkable tubes are good. Usually, we recommend consumers to choose high-voltage heat-shrinkable tube products from big manufacturers and big brands. The reason is that high-voltage heat-shrinkable tube involves the safety problem of tens of thousands of volts, and large manufacturers can provide better protection for product quality and safety no matter the production capacity, research and development capacity, technical level or pre-sales and after-sales service.

To sum up, in the purchase of high voltage heat shrink tube, mainly consider the required material, specifications, size, voltage level requirements, and combined with the production strength and comprehensive level of the manufacturer comprehensive consideration, so as to buy the high voltage heat shrink tube with good quality performance, safety factor is guaranteed, in line with the procurement needs. I hope that the above suggestions can provide helpful help for consumers to choose high pressure heat shrinkable tube accurately.
