Busbar Insulation Sleeve (PVC/Heat Shrink)

Busbar insulation is crucial for the proper functioning of electrical systems, particularly in environments requiring protection against electrical faults, environmental factors, and thermal stress. Our Busbar Insulation Sleeves, made from high-performance PVC and heat shrink materials, provide a durable solution for these challenges. 

Materials

PVC (Polyvinyl Chloride) and heat shrinkable polyolefin, offering electrical and thermal insulation.

Surface Finishes

Smooth, glossy, matte, or textured finishes, ensuring durable surface protection and easy handling.

Compliance Standards

Meets IEC 60229, UL 224, RoHS, CE certifications for electrical safety and environmental compliance.

Cross-Section Area (A)

Ranges from 10 to 250 mm² depending on busbar size, ensuring adequate insulation and protection.

Mass per Meter (m)

Varies between 0.05 to 1.5 kg/m based on material type, thickness, and busbar dimensions.

Product Description

Busbar insulation prevents electrical contact between conductive components, reducing the risk of short circuits and faults. The PVC material provides high dielectric strength, which allows it to withstand high voltages without breaking down. Heat shrink sleeves tightly conform to the busbar, ensuring consistent electrical isolation even in tight spaces. This insulation maintains performance in high-voltage environments, minimizing operational risks. 

Moment of Inertia (Ix / Iy)

The bending resistance ranges from 1.2 × 10⁻⁶ to 2.5 × 10⁻⁶ m⁴ along the Ix and from 1.0 × 10⁻⁶ to 2.3 × 10⁻⁶ m⁴ along the Iy.

Section Modulus (Zx / Zy)

Zx: 2.5 x 10³ to 3.0 x 10³ mm³, Zy: 2.2 x 10³ to 2.8 x 10³ mm³, indicating bending strength.

Radius of Gyration (ix / iy)

ix: 3.2 to 4.5 mm, iy: 3.0 to 4.2 mm, assessing distribution of mass for effective insulation.

Max. Axial Load (Euler Buckling)

Can withstand axial loads from 250 to 500 N, preventing buckling under compressive forces.

Max. Load at Slot (Shear Test)

Supports loads of 300 to 600 N, testing the sleeve’s ability to resist shear stress at slots.

Torsional Constant (J)

Ranges from 6.5 x 10⁻⁶ to 9.8 x 10⁻⁶ m⁴, indicating the material’s resistance to torsional deformation.

Max Torque (Torsional Load Limit)

Maximum torque capacity ranges from 10 to 50 N·m, ensuring torsional stability in applications.

Elastic Deflection (100 N Load)

Deflection between 2 to 5 mm, measuring sleeve flexibility under a 100 N applied load

Dynamic Load Rating

Rating from 200 to 800 N, representing sleeve performance under dynamic or fluctuating loads.

Compatibility Tolerance

Tolerances range from ± 0.1 mm for heat shrink sleeves to ± 0.3 mm for PVC-based sleeves.

Machining Precision Grade

Precision machining with tolerances of ± 0.2 mm for PVC and ± 0.3 mm for heat shrink variants.

Fatigue Life (Slot Edge)

Designed for 50,000 to 200,000 cycles, indicating long-term durability in repetitive applications.

Thermal Expansion (ΔL @ ΔT=50°C)

Thermal expansion rates of PVC at 0.07 mm/m, and heat shrink material at 0.09 mm/m.

Slot Pull-Out Resistance

Resistance from 50 to 100 N, ensuring the sleeve stays securely in place during use.

Max Load Bearing at Corner Joint

Can withstand 150 to 500 N, depending on the sleeve thickness and material characteristics.

Technical Advantages

Electrical systems often face harsh environments with moisture, dust, chemicals, and extreme temperatures. PVC-based sleeves offer a strong barrier against moisture, corrosion, and abrasion. Heat shrink sleeves provide an additional protective layer, creating a tight seal that prevents contaminants from entering. These sleeves maintain their protective properties in environments with shifting conditions, ensuring reliable performance over time. 

Overheating is a major concern in high-current applications. Excessive heat can cause insulation to degrade, leading to electrical failures. Heat shrink sleeves are made from materials that can withstand high temperatures without losing their insulating properties. PVC sleeves are also thermally resistant, making them ideal for environments where temperature fluctuations are moderate but still need reliable protection.

Industry Applications

Renewable Energy Systems

In solar and wind power installations, busbar insulation sleeves safeguard conductors from environmental stress, maintaining consistent electrical performance. 

Automotive Electrical Systems

Used in high-current automotive applications, these sleeves ensure proper insulation and thermal protection for busbars in electrical control units. 

HVAC Systems

Insulation sleeves protect busbars in heating, ventilation, and air conditioning systems, preventing electrical faults in complex control circuits. 

Railway Electrification

Busbar insulation sleeves prevent electrical faults in railway signaling and power distribution systems, ensuring safe and efficient train operations. 

Data Centers

PVC/heat shrink sleeves provide insulation for busbars in data center power distribution units, minimizing the risk of electrical failures. 

Marine Electrical Systems

In marine applications, insulation sleeves protect busbars from corrosion and environmental factors, ensuring safe power distribution on vessels. 

Precision Fit and Customization

A precise fit is crucial for effective insulation. Gaps or loose fittings can expose the busbar, leading to faults. Heat shrink sleeves shrink evenly when heated, creating a tight fit around the busbar. They are engineered to shrink only in the radial direction, which prevents distortion. These sleeves can be customized for different busbar sizes, shapes, and lengths, ensuring the perfect fit for each application. 

Busbar insulation must withstand mechanical stresses such as vibrations and impacts. PVC offers excellent tensile strength and resistance to abrasion. Heat shrink sleeves, once applied, bond securely to the busbar, preventing slippage or detachment. This mechanical durability ensures long-lasting protection even in high-vibration environments.
