1. The bus bar heat shrinker features high dielectric strength, leakage and short circuit prevention, stable power transmission of both indoor and outdoor 10kV-35kV.
2. The product is characterized by high tensile strength, impact resistance, can withstand external mechanical forces, greatly reduce the harm of collisions and abrasion to the busbar.
3. After heating and shrinking, the product will form a tight protective layer, having good moisture resistance, dustproof and weather resistance, and can adapt to the demanding condition of industrial field use for a long time.
In 10kV-35kV power systems, busbar insulation layers are repeatedly subjected to high voltage, temperature, moisture, pollution, etc. These stresses can cause insulation failure. The aging of conventional materials eventually results in insulation degradation. That can lead to leakage, flashover, and even short circuits. Insulation failure due to insulation ageing is one of the primary causes of sudden power trips which have adverse economic impact and at the same time may endanger lives.
Our solution:
Busbar heat shrink utilizes top-quality insulation materials characterized by superlative dielectric strength (breakdown voltage 25 kV ≥ per mm) and outstanding tracking resistance as key properties. After being heated, it tightly shrinks into a smooth, compact protective layer, providing high tensile strength and impact resistance beside moisture and weather resistance. It prevents bus bars from electrically aging by offering good electrical and mechanical support along a lasting stable insulation and protection system that guarantee power system's performance, safety, and economy.

Product Definition:
A heat-shrinkable type of sleeves is especially suited and designed for busbar protection. This kind of heat-shrinkable sleeve mainly offers insulation protection of various buses in an electric system which is operating either at high or low voltage. Due to its high-performance insulation material, once heated it shrinks and closely covers the surface of the busbar making a highly dependable electric insulation coating. Such sleeve not only makes busbar electrical safety more secure but also protects them from environmental damage that could come from factors like water, dirt, or mechanical impact. Heat-shrink sleeves are typically employed in distribution cabinets, power transformers, and power-related industrial equipment besides that.

Key Advantages of the Busbar Heat Shrink Sleeve:
1. Excellent weather resistance and protection.
The sleeve is composed of high-performance insulating materials to offer great resistance to tracking, aging, and corrosion. When used over a long working time period, it keeps the busbar free from the effect of an electric field stress, ambient conditions, and chemical corrosion, thus contributing to prolonging the life of the busbar and enhancing its overall performance.
2. Reliable insulation protection.
The heat shrink sleeve applied on busbars is specially tailored for busbars in switching gears, substations, as well as high-voltage power distributing equipments (HV-PDs). It creates a durable insulating layer by closely wrapping around and thereby significantly lowers the chances of leakage and short circuit faults due to lack of sufficient busbar spacing in addition to contact with foreign objects. Consequently, this enhances the level of safety of the electrical appliances.
3. Long-term stable operation over a wide temperature range.
Operating temperature ranges continuously from -45℃ to 105℃ is what the product is designed for. With such an ability, it can easily cope with low and high temperatures, the main factors, of course, that are responsible for environmental conditions. Its excellent insulation property and high mechanical strength are preserved even in different situations, which, along with other factors, ensure that the power system will be operating steadily and efficiently without interruption over a period of time.
4. Quick shrinkage and convenient installation.
Busbar heat shrink sleeve starts to shrink at 110 ℃ and totally shrinks up to 130 ℃. Upon heating, it uniformly sticks to the busbar surface, creating a close and solid protective cover. In this way, work progress gets accelerated and it is perfectly fine for the speedy onsite installation.
5. Environmentally friendly and safe, meeting international standards.
Our heat shrink sleeve for busbars is RoHS compliant, meaning it restricts the use of hazardous substances. We have ensured the heat shrink sleeve can still provide the electrical performance and protective feature needed for any application at the same time, it also supports further development of green and clean electrical equipment.

What Are the Application Areas of Busbar Insulation Sleeves?
·High-voltage substations.
Primarily providing insulation protection and safety isolation, it prevents high-voltage arc discharge by wrapping the busbar, ensuring the safe transmission of high-power electrical energy and the stable operation of substation equipment.
·Industrial power distribution.
Providing insulation protection for busbars in industrial environments such as factories and refineries, effectively preventing electrical faults caused by dust, moisture, or equipment overload, ensuring the efficient operation of production line machinery.
·Renewable energy facilities.
Used in wind and solar power plants, busbar systems contribute to the resistance of environmental degradation and the transmission of electricity. They work by safeguarding conductive circuits against harsh weather conditions such as sandstorms and salt spray and thus enabling the reliable collection and distribution of solar power and other renewable energy sources.
