HXPnR-H 8 Series Single-Pole Combined Sliding Contact Line
Darui Electric recommends
HXPnP, R-H type protective safety sliding contact line, whose conductive main body is an aluminum profile with an "H" cross-section, hence also known as the "H" type energy-saving sliding line device. Energy saving is relative to the sliding contact line with angle steel as the main body, as the loss of electrical energy during transmission is greatly reduced. The resistivity of aluminum is much lower than that of steel, and its specific gravity is small. Rolling aluminum into an "H" shape ensures a certain conductive cross-sectional area while improving overall rigidity and strength. However, the surface hardness of aluminum is low and it is not wear-resistant. To make the aluminum substrate practical as a conductive sliding contact line, the "H" shaped middle beam is made into an arched shape, and wear-resistant stainless steel profiles are embedded at this location according to specified process procedures. This "H" shaped stainless steel profile serves as the friction and transmission surface for the conductive block in the current collector. Its embedding process ensures a tight combination of stainless steel and aluminum profile, so that the current introduced from the aluminum profile passes through the stainless steel body, and the conductive block in the current collector that remains in contact with it transmits the current through frictional contact, ensuring the continuity of current during the operation of lifting machinery.
The conductive sliding line is protected along its longitudinal direction by ABS plastic as a whole, except for the lower opening where it contacts the current collector. Therefore, after installation, there is no exposed conductive part of the contact line, which brings great convenience to installation and maintenance. At the same time, the overall plastic shell protection (except for the opening) prevents dust accumulation and provides protection against rain, dew, ice, and snow. The connection between guide rails is made by a dedicated rail connector that allows both the rail and the plastic shell to be inserted together, and its connection end is also safe and reliable.
