The function of Busbar heat shrink sleeve and its application classified by material

With the continuous development of science and technology, the manufacturing industry is gradually iterating towards globalization, informatization, and automation. In production and life, people not only focus on production efficiency and labor comfort, but also prioritize safety. In this context, the application scenarios of PE heat shrink tube insulated busbar are constantly expanding. As a basic protective material, its most common use is as an insulation material for voltages less than 600V, while also providing rust prevention protection for metal components. With its convenient use characteristics, it has been widely integrated into multiple fields such as electronics, communication, machinery, manufacturing, and power, and has become an indispensable protective product in modern production and life.

The Heat shrink tube polyolefin busbar has core features such as softness and ease of operation, high temperature shrinkage, flame retardant insulation, rust and corrosion prevention. Its function is mainly focused on insulation protection and component protection. It can be widely used for insulation protection of various wire harnesses, welding points, inductors, as well as rust and corrosion prevention treatment of metal tubes and rods, effectively extending the service life of components and equipment and avoiding electrical safety hazards.

From the perspective of working principle, the polymer materials used in Busbar insulating tubing will exhibit different states with temperature changes. At room temperature, they are in a glassy state and have properties similar to plastics; After heating, it transforms into a highly elastic state with properties similar to rubber. During the production process, heat the heat shrink tubing to a high elastic state and apply a load to expand it. After rapid cooling, fix it in a glassy state; When heated again during use, the material will return to a high elastic state without any load, and it will automatically retract and tightly adhere to the protected component.

Busbar insulation sheet, as a specialized category of heat shrink tubing, is a professional and reliable insulation protection solution for power equipment such as control cabinets and substations. In theory, all live exposed metals in control cabinets require insulation protection, and busbar heat shrink tubing can accurately meet this requirement. Its core material is radiation cross-linked polyolefin, prepared through cross-linking process. All busbar insulation heat shrink tubes, sheets, non heat shrink typical products, and joint boxes are made of this type of material. This material has good thermal stability, flame retardancy, flexibility, non cracking, and resistance to electrical traces, as well as excellent electrical properties, which can fully meet the engineering insulation requirements of various switchgear. It is widely used in the fields of electronics, communication, machinery, manufacturing, power, etc., especially suitable for insulation protection of substations and high and low voltage switchgear busbars.

In practical applications, the Heat shrink busbar can effectively solve multiple pain points in the operation of power equipment: firstly, increasing the insulation performance of the busbar to prevent short circuit accidents caused by small animals touching it; The second is to prevent condensation flashover and pollution flashover, and adapt to equipment protection in harsh environments; Thirdly, isolate the live gap to prevent maintenance personnel from accidentally entering the live area and causing safety accidents; The fourth is to enhance the insulation performance between switchgear phases, effectively reduce the volume of switchgear, and optimize equipment space layout; Fifth, provide special protection for complex electrical contacts to prevent foreign objects from overlapping and causing malfunctions; The sixth is to achieve comprehensive anti-corrosion of the busbar, block external corrosive media, and extend the service life of the busbar.
 

The material of heat shrink tubing directly determines its performance and application scenarios. Currently, polyolefin is the mainstream material in the industry, among which radiation cross-linked polyolefin is a specialized material for busbar heat shrink tubing, which is specially adapted to high-voltage power equipment such as substations and high and low voltage switchgear. It undertakes core functions such as Customized busbar insulating tube insulation, corrosion prevention, and spacing optimization, perfectly matching the strict insulation requirements of power equipment. Ordinary polyolefin heat shrink tubing is mainly suitable for low voltage scenarios below 600V, used for basic insulation and rust prevention of wire harnesses, solder joints, metal components, and to meet the basic protection needs of fields such as electronics, communication, and mechanical manufacturing.

Based on the differentiated needs of different scenarios, the polyolefin heat shrinkable tubing can further expand the scope of adaptation after process optimization: it can be adapted to the Heat shrinkable busbar insulating tape of the electric control cabinet and substation, focusing on strengthening the flame retardant, anti tracking, anti-aging performance, and can withstand the temperature fluctuations in the operation of equipment; Suitable for ordinary polyolefin heat shrink tubing in the fields of electronics and communication, with a focus on improving flexibility and insulation, making it easy to tightly wrap and protect wire harnesses and solder joints; Suitable for polyolefin heat shrink tubing in the field of mechanical manufacturing, with a focus on enhancing wear resistance and corrosion resistance, it can effectively protect metal components from external wear and medium erosion, achieving comprehensive protection.
