In the competitive world of electrical contracting and switchgear assembly, installation speed and accuracy are paramount. The Volsun MPRS series busbar heat shrink sleeve is engineered to streamline these processes, offering a versatile range of solutions that adapt to the varied geometries of modern busbar systems. From the smallest low-voltage connectors to massive high-voltage substation bars, MPRS insulation tubing provides a professional, tight-fitting finish with minimal effort.

Seamless Installation Logic The core of the MPRS series’ efficiency lies in its 2:1 heat shrink ratio and low shrinking temperature. The 1kV series begins to shrink at just 70C, while the 10kV and 35kV series operate in a range of 84C to 120C. This allows installers to use standard industrial heat guns or ovens to achieve a fast, uniform recovery.

• Flexible Geometries: Because the polyolefin material is soft and high-strength, it easily slides over L-shaped bends, U-shaped corners, and bolted joints.
• Controlled Axial Change: With an axial change rate of only -8% to +8%, engineers can cut the tubing to precise lengths, knowing it will stay stable during the heating process.

Comprehensive Size and Color Customization 

No two projects are identical, which is why Volsun provides a massive range of specifications.

• Size Range: Our catalog spans from Φ8.0mm for small low-voltage wiring up to Φ180.0mm for high-capacity industrial busbars.
• Visual Identification: Standard colors include red, yellow, and green, aligning with international phase-coding standards. We also offer black, white, and blue, and can customize colors to meet specific branding or safety requirements.
• Custom Packaging: While standard plates come in 20m or 25m lengths, we provide customized packaging to reduce waste on the assembly line.

By choosing a busbar sleeve that combines ease of installation with a vast array of technical specifications, companies can reduce labor costs and improve the visual and technical quality of their electrical installations. Whether you are insulating a simple low-voltage busbar slot or complex 35kV high-voltage equipment, the MPRS series offers the adaptability needed for the modern job site.
