H-shaped aluminum alloy sliding contact line is a power transmission equipment used for power supply of mobile equipment. Its conductive main body is an aluminum alloy profile with an "H"-shaped cross-section, so it is also called an "H"-shaped energy-saving sliding line device. This sliding contact line has the following characteristics and advantages:
Remarkable energy-saving effect: The resistivity of aluminum alloy is much lower than that of steel, and its specific gravity is small, so the power loss during power transmission is greatly reduced, with significant energy-saving effect.
High mechanical strength: The H-shaped aluminum alloy sliding contact line has excellent electrical conductivity and mechanical strength, and is suitable for occasions with large current, fast running speed and harsh environment.
Strong wear resistance: Since the surface hardness of aluminum alloy is low and it is not wear-resistant, the beam of the H-shaped sliding line is made into an upward arch shape, and stainless steel profiles with strong wear resistance are embedded through special processes to ensure that the friction and power transmission surface of the conductive block is wear-resistant¹⁴.
Perfect protective measures: It is usually equipped with a PVC insulating shell, which plays a protective role such as dust-proof, rain-proof and anti-corrosion, ensuring the safe and stable operation of the equipment.
Wide range of applications: It is widely used in industries such as metallurgy, shipbuilding, cranes, automobile manufacturing and port loading and unloading, and is especially suitable for occasions with large current, high usage frequency and fast running speed.
