Angle steel sliding contact line

‌H-type single-pole aluminum sliding contact line‌ is a device used to ensure continuous current transmission during the operation of lifting machinery. Its conductive main body is an aluminum profile with an "H"-shaped cross-section. This design is not only energy-saving but also practical, providing an efficient and reliable power transmission solution for modern industries‌.
Structural composition
The H-type single-pole aluminum sliding contact line is mainly composed of the following parts:
‌Conductive main body‌: Made of aluminum profile with an "H"-shaped cross-section. Aluminum is widely used due to its low resistivity and small specific gravity‌.
‌Insulating shell‌: Protected entirely by PVC plastic, only the conductive part is left at the lower opening where it contacts the current collector‌.
‌Current collector‌: Used to transmit the electric energy in the sliding contact line to electrical equipment through sliding contact‌.
‌Connection components‌: Including suspension and fixing devices, etc., used for installing and connecting the sliding contact line‌.
Working principle
The H-type single-pole aluminum sliding contact line transmits electric energy through the conductive main body. The current is introduced from the aluminum profile, and continuous power transmission is realized by contacting the embedded stainless steel strip with the conductive block in the current collector. Its design ensures the stability, safety and continuity of current transmission during the operation of mobile equipment‌.
Product features
‌Energy-saving‌: Compared with traditional angle steel sliding contact lines, aluminum has low resistivity and low power loss‌.
‌Large current carrying capacity‌: It can meet the needs of high-current mobile power-receiving equipment‌.
‌Fast running speed‌: The current collector has good heat dissipation performance and high running speed‌.
‌Excellent protective performance‌: The protection grade can reach IP23, with functions such as dust prevention, water prevention and anti-ash accumulation‌.
‌Long service life‌: Stainless steel and aluminum are compounded by special equipment to avoid electric corrosion, and the service life can reach more than 10 years‌.
Application fields
The H-type single-pole aluminum sliding contact line is suitable for occasions with large current, high use frequency, fast running speed and poor environment, such as industrial places like ports, steel mills and waterworks, as well as mechanical equipment such as large-tonnage cranes, bridge cranes and loading bridges‌.
