Shanghai Wellco International Limited presents a high-quality insulation protection material suitable for various applications. Our product is made of cross-linked modified polyolefin, ensuring durability and reliability.
With an operating temperature range of -40ºC to 125ºC, our material can withstand extreme conditions. It has a contraction temperature above 70ºC, allowing for easy installation and maintenance.
The contraction ratio of 2:5:1 ensures a tight and secure fit, providing excellent insulation and protection. Our material is designed with high-voltage resistance, corrosion resistance, and high insulation properties, making it ideal for transformer station buses and high/low voltage switch cubicle buses.
By compacting the structure of the switch cubicle and reducing the distance in between, our material effectively prevents accidental short circuit incidents, ensuring the safety of your equipment and personnel.
Choose Shanghai Wellco International Limited for reliable and high-performance insulation protection. Trust our product to meet your needs and exceed your expectations.
