Cardboard spacer bars

Cardboard spacer bars are made of high-strength cardboard materials, which are usually specially treated to have excellent physical properties. Through precise processing techniques, the cardboard is cut and formed into spacer bars of specific shapes and sizes, and installed and fixed at precise intervals. They are used to construct the oil duct structure within electrical equipment, and are widely applied in large Power Transformers, reactors, and other equipment. They can optimize the oil circulation path in electrical equipment such as transformers, improve heat dissipation efficiency, and thus enhance the stability and reliability of the equipment.

Product Features

Cardboard spacer bars have excellent performance. Made of special cardboard materials, they feature good insulation, effectively blocking current conduction and preventing leakage to ensure electrical safety. With high mechanical strength, they can withstand oil flow pressure and equipment vibrations, maintaining stable oil duct operation. The rational layout design allows insulating oil to flow evenly through the heating parts, improving heat dissipation efficiency, reducing equipment temperature, and extending its service life. Moreover, the materials are oil - resistant and corrosion - resistant, remaining stable without deformation or aging even after long - term exposure to insulating oil, ensuring stable operation in complex environments.

Product Classification

By Material:

Ordinary Cardboard Material: Cost-effective with basic insulation, ideal for standard electrical equipment and cost-sensitive applications.

Special Reinforced Cardboard Material: Processed for enhanced strength and corrosion resistance, suitable for high-performance requirements and harsh environments.

By Oil Duct Spacing:

Small-spacing Type: Designed for equipment with concentrated heat sources, enabling efficient heat dissipation through tight oil circulation.

Large-spacing Type: Suited for evenly-heated equipment, reducing resistance to achieve rapid oil circulation.
