In core areas such as power transmission and industrial control, the insulation protection of busbar joints is undoubtedly the key to system safety. Volsun's MPPB series busbar joint protection junction box uses advanced radiation cross-linked polyolefin materials to provide full voltage level solutions covering 1kV to 35kV, effectively resisting environmental erosion and preventing accidental short circuits, and building an indestructible "safety barrier" for the busbar system.

With a unique structural design, Volsun provides a variety of shapes such as I/T/L types to accurately adapt to various busbar connection types. The snap-on design ensures that the protection box fits tightly with the busbar, eliminates insulation dead corners, effectively prevents safety accidents caused by small animals or debris, and can be quickly installed without the help of any tools, greatly improving construction efficiency.

Volsun busbar junction are usually made of radiation cross-linked polyolefin materials and have the following advantages:

• Excellent electrical performance: breakdown strength ≥20kV/mm, ensuring stable operation in high voltage environments.
• Excellent volume resistivity: volume resistivity ≥10¹⁴Ω・cm, excellent resistance to electric carbon traces, further ensuring electrical safety.
• Flame retardant and safe design: reaching UL94 V-0 flame retardant rating, low smoke and halogen-free design, providing strong protection for fire safety.
• Excellent high and low temperature resistance: continuous use temperature range covers -55℃~125℃, no fear of extreme climate challenges, long-term outdoor use performance is stable and does not decay, ensuring long-term reliable operation.
• Excellent durability: tensile strength is still more than 6.9MPa after 168 hours of 130 degrees thermal aging test; no cracks or dripping after thermal shock test, stable and reliable in high temperature environment.

Volsun busbar protection cover has different voltage levels to better meet customer needs:

• 1kV low-voltage busbar protection box: suitable for compact space, widely used in low-voltage switchgear and bus duct.
• 10kV medium-voltage busbar protection box: suitable for medium-voltage distribution equipment and substations, providing reliable insulation protection.
• 35kV high-voltage busbar protection box: can effectively shorten the phase-to-phase distance by about 30%, is resistant to high-voltage shock, and is mostly used for high-voltage busbars and power transformers to improve safety performance.

Volsun busbar protection box has passed RoHS certification, and the busbar junction box is harmless and environmentally friendly. Welcome to contact us for more details!
