What criteria can be used to measure the quality of the safety contact line?

Temperature contact lines are mainly divided into three categories: single pole contact lines, multi-pole contact lines and rigid body contact lines. In fact, there are many sub-categories under each category, such as single pole contact lines, h-type contact lines, m-type contact lines, c-type contact lines, u-type contact lines and so on. Multipole sliding contact line is divided into tube multipole sliding energy line, row multipole sliding contact line and no seam multipole sliding contact line. The rigid sliding contact lines are divided into dovetail groove rigid sliding contact lines, several lines of rigid sliding contact lines and ladle aluminum sliding contact lines.Conductor area, conductor thickness.

Obviously, the larger the conductor area, the better the heat dissipation. The thicker the conductor, the stronger its conductivity. When buying slide contact line, must observe the slide contact line conductor sectional area, but also to observe the thickness of the conductor, do not exclude, some manufacturers, the current of the small slide contact line as a large current of the slide line.

Overall appearance design. This item does not seem to play much role, but it actually occupies a certain share. The overall appearance design of the sliding contact line conforms to most engineering environments, and the appearance design is conducive to the protection of the sliding contact line, and it also adds highlights from the perspective of aesthetics. This will improve the competitiveness of the product in the slippery line market.

Conductor aluminum alloy material quality and source. This one element, also be the main factor that decides slippery contact line price, aluminium alloy conductor material is better, the price is high also, opposite also is same.

The safety contact wire is safe, reliable and has excellent mechanical and electrical properties, which is convenient for installation and maintenance. The phase spacing is 80mm, the protective shell is made of engineering plastic and aluminum alloy, and the conductor is aluminum alloy (inner inlaid stainless steel strip) or pure copper. Not affected by rain, snow and frost, suitable for outdoor, water fog, acid fog, conductive dust and other poor environment. Specifications below 300A can be made according to user needs of various radius of the circle, arc.

Safety sliding contact line for moving equipment power supply, consists of two parts, sliding guide rail (fixed part, into the power supply, often guide by single 4 m long/root or can be connected with the 6 m/root), collector (sliding parts, can be in within the sliding track or move and take electrical contact with copper, collector for connected to the mobile motor).

At present, safety sliding contact line (tube type, closed), unipolar combination sliding contact line, rigid 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 and so on are generally adopted.

The quality of safety contact line can be measured according to the following standards:

1. Service life of carbon brush -- it belongs to consumables, and the driving distance affects the maintenance cycle of the equipment;

2. Shell quality of sliding contact line -- applicable temperature, environment, etc.

3. Performance of coke appliances -- mainly from the service life of wheels, the design of turning wheels and whether the collector can meet the requirements of various environments;

4. Expansion of slip contact line -- expansion problem should be considered after the length exceeds 100 meters;

5.Voltage drop problem - the voltage drop varies according to the length of each copper strip.
