Classification and performance characteristics of safety contact line

Safety sliding contact line is safety sliding contact line (tube, closed), unipolar combination sliding contact line, steel body sliding contact line, multistage tube safety sliding contact line, no seam safety sliding contact line, cable safety sliding contact line, i-beam cable pulley, etc. Safety contact wire is used for dust, humidity and other environment, can be equipped with dust seal and hand protection (contact wire is close to the tear line from the person should be equipped with hand protection), collector operating speed is less than 300 meters/min.

Safety slip contact line can be divided into the following three types:

Unipolar combination security sliding contact line - easy installation, speed, speed of up to 500 m/min (imports sliding contact line can reach), unipolar aluminum alloy safety sliding contact line and unipolar copper alloy safety sliding contact line is mainly used electric double beam bridge crane, especially for driving run faster more applicable, current can be from 200 a to 2000 a, is a sliding contact line is more widely used.

Steel body safety slip contact - for high current equipment, current up to several thousand amperes. The safety slip contact line of high temperature steel body is mainly applicable to the harsh environment of high temperature and high corrosion, especially for the steel metallurgy and other industries, the current is higher than 4000A and has the characteristics of high corrosion resistance, high temperature resistance and wear resistance, but its cost is too high.

Multipole tube safety sliding contact line is the tube sliding contact line - according to the number of different poles combination, the current can also be up to 1000 amperes. Multi-pole tube safety sliding contact line is mainly applicable to the current, is a large mobile equipment, such as electric single-beam crane single-beam suspension crane, electric hoist and other light and small equipment.
