How to select the collector according to the current of the slide contact line?

The conductive body of the monopole combined sliding contact line is the aluminum profile with "H" section, so it is also called "H" type energy-saving sliding contact device. Compared with the sliding contact line with Angle steel as the main body, the loss of electric energy in the transmission process is greatly reduced. The resistivity of aluminum is much lower than that of steel, and the specific gravity is small. The aluminum is rolled into H" shape, which can improve the overall rigidity and strength on the basis of ensuring a certain conductive cross-sectional area. Unipolar combined sliding contact wire aluminum surface hardness is low and not wear resistance.

Monopole combination of sliding contact line collector mainly consists of shoe box, shoe piece, spring, collector bracket, collector back to support parts and other components, collector is divided into heavy collector and light collector choose light collector return is heavy collector, is determined according to the current of the sliding contact line.

Monopole combination of contact line in the selection of contact line collector, must consider whether and contact line supporting manufacturers, do not randomly choose the collector, otherwise it will affect the normal use of cranes and cranes, but also cause greater damage to the contact line. Monopole combination of the brush above the collector is composed of copper carbon base pressure, after purchase to check and the model of the contact line is consistent, because the collector itself belongs to consumables, long-term use will wear brush, so to check regularly, brush above the collector wear degree, and replace regularly.

In order to satisfy the practicability of aluminum substrate as a conductive unipolar combination sliding contact line, the upper arch is made in the h-shaped middle beam, and the stainless steel profile with strong abrasion resistance is embedded here according to the specified process procedure. The "H" shaped stainless steel profiles as guide electrical conductive block in friction transmission of power, the embedded technology to ensure the close combination with stainless steel and aluminum, unipolar combination sliding contact line from import aluminum electric current through the stainless steel body and keep in contact with the guide of electrical conductivity of the block in the heart of the friction contact current transfer out, to ensure the hoisting machinery in current in the process of continuous operation.

The flat cable is made up of flat cable, four-wheel trolley for carrying cable and guide rolling. The flat cable is made of non-flame retardant material, which can be used in indoor and outdoor areas and places where oil is in contact with. It has certain weather resistance performance.

Unipolar combination sliding contact line along the direction of slip line running with ABS plastic protection as a whole in addition to the bottom opening and guide electrical contact, therefore no exposed portion of a conductive contact wires after installation, bring great convenience to installation and maintenance, at the same time, the whole plastic shell protection, make the sliding contact line does not have dust and rain and dew, snow, ice, the function of invasion, unipolar combination sliding contact line is the connection between the guide and guide for the guide rail connector can make the guide rail with plastic shell into the meantime, its even end of safe and reliable.
