Production process
Material Selection
We start by carefully selecting high-quality materials for PVC Insulation Busbar insulating products. For PE Heat Shrink Tube Insulated Busbar and Heat Shrink Tube Polyolefin Busbar, we use cross-linked polyolefin, which offers excellent mechanical strength, chemical resistance, and insulation properties.
Extrusion and Expansion
The selected material is extruded into a tube form and then expanded to a larger diameter. This process involves heating the tube and stretching it to create a "memory" effect, allowing it to shrink back to its original size when reheated.
Shrink Ratio Calibration
The tubing is calibrated to achieve a specific shrink ratio, typically 2:1 or 2.5:1, ensuring a snug fit over the PVC Insulation Busbar. This ratio is crucial for providing a secure and consistent insulation layer.
Quality Testing
Each batch of tubing undergoes rigorous testing for tensile strength, elongation, dielectric strength, and other key properties to ensure it meets industry standards.

Standard Configuration
1. Material and Construction: Our standard Heat Shrink Tubing Bar is made from high-quality cross-linked polyolefin, offering excellent insulation and protection against electrical leakage and short circuits.
2. Dimensions and Shrink Ratio: The tubing is available in various sizes with an expanded inside diameter ranging from 15mm to 235mm and a shrink ratio of 2:1 or 2.5:1. This allows it to fit snugly over rectangular, square, or round busbars.
3. Operating Temperature Range: Our products are designed to operate reliably within a temperature range of -55°C to +125°C, making them suitable for both indoor and outdoor applications.
4. Compliance and Safety: All our insulating busbar products meet international standards and environmental protection.
type summary
PE Heat Shrink Tube Insulated Busbar: This type is made from cross-linked polyethylene, offering high dielectric strength and resistance to chemical corrosion. It is ideal for applications requiring high insulation performance.
Heat Shrink Tube Polyolefin Busbar: Constructed from cross-linked polyolefin, this tubing provides excellent mechanical strength, flexibility, and flame retardancy. It is suitable for use in switchgear and substations.
Heat Shrink TubingBar: Available in various wall thicknesses, this tubing is designed to provide robust insulation and protection against flashovers and induced discharge. It is particularly useful in confined spaces.
PVC Insulation Busbar: While not as flexible as polyolefin, PVC offers good insulation properties and is often used for applications requiring additional chemical resistance.
Products feature
1. Customization Options: We offer a wide range of customization options for our insulating busbar products, including different colors (such as red, yellow, green, and blue) to distinguish between different phases of busbars.
2. Installation Flexibility: Our Heat Shrink Tubing Bar can be easily installed using standard heat application methods, such as ovens, gas torches, or hot air guns. This flexibility makes it suitable for both large-scale production and field installations.
3. Environmental Resistance: Our products are designed to withstand harsh environmental conditions, including exposure to moisture, UV radiation, and corrosive chemicals. This ensures long-term reliability and minimal maintenance.
4. Flame Retardancy: All our insulating busbar products are flame retardant and halogen-free, meeting stringent safety standards.
