16mm² busbar Integrated Power and Control Line hoist cable
Integrated Power and Control Line Hoist Cable Overview
When hoist cage moving up and down, it needs power continuously. The Sliding Contact Line is a system that supplying power to the hoist lifts. The conductive conduits are installed on the mast, and the current collector is assembled on the cage to get power from them. The current collector operates synchronously with the moving cage, so the power is obtained from the conductive conduits to make the hoist move continuously. The sliding contact line is the device that composed of current collector, conductive conduits which hold conductive rails, and relative components.
Features of Busbar
* Safe: The Sliding Contact Line will not be affected by wind, rain and other bad weather. The good insulation performance of it ensures safety of the maintenance personnels.
* Reliable: The conductive rails made of special aluminum alloy profile are with excellent conductivity, rapid heat dissipation, low impedance and line loss. The electric brushes made of metal graphite material are with high conductivity and high wear resistance. The current collector moves flexibly in the conduit and is with good directional performance. The contact arc and the series arc phenomenon of the system are controlled effectively.
* Economic: The structure Sliding contact line device greatly reduces the loss of electric energy. The length of Sliding Contact Line can be extended according to mast height. Meanwhile, the conductive conduits can be segmented replaced, no need to change the whole cable if local damage.
* Convenient: The Sliding Contact Line integrates multistage busbar in a conduit and parts of the system, such as fixed brackets, connecting clamps and suspension devices, etc. are provided with common components, can be assembled/dismantled, commissioned and repaired easily.

Common Troubleshouting and solutions of passenger and material hoists Slide Contact Line
|Sr. No.||Descriptions||Inspection Items||Fault Analysis||Solutions||Required Part Name||Remarks|
|1||No power supply or phase loss||Whether is length of brush in the current collector is less then 11mm?||Abrasion of brush?||Replace the brush||Carbon Brush|
|Whether the aluminum bar is well connected in the position of sliding contact line joints?||Change the internal contacting spot, adjust the aluminum bar||Contacting Spot|
|Whether the carbon brush can not telescope smoothly because of rubbish inside of the current collector?||Open the current collector and clean inside.|
|Whether the spring of carbon brush is broken?||Replace the spring||Srping|
|Whether there is pock mark or burnt mark on the steel part of aluminum bar?||If there is only slight pock mark or burnt mark, make the steel part of aluminum bar become smooth by using oilstone. If there is serious burnt, please change the aluminum bar.||Aluminum Bar|
|Whether it is not frequency converting controlling system?||Install double current collector||Current Collector|
|Whether it is high speed building hoist?||Increase quantity of current collector||Current Collector|
|2||Sliding Contact Line is bent||Whether line is descending||Screw of steel fastener is loose or missing?||Fasten the screw|
|Anti-drop suspender is loose or missing?||Reset the anti-drop suspender and check whether it is installed every 18m||Anti-drop suspender|
|Distance between the steel fastener and sliding contact line joint is too far?||Loosen the steel fastener from top to bottom, adjust the distance between joints and steel fastener. Install more steel fastener|
|Conduit Fastener is forgotten to install? Make sure that there is one conduit fastener on each mast section||Install Conduit fastener||Conduit Fastener|
|3||Power Off suddenly when the building hoist is traveling||Inspect the connection of Sliding contact lines in this position||Whether connector screw is loose?||Fasten the screw|
|Whether the contacting spot is burnt||change the contacting spot||Contacting Spot|
|Whether the spring chip is broken?||Change the Spring Chip||Spring Chip|
|4||Circuit breaker tripped in rainy weather||1, Check whether there is rubbish in the inlet connector or internal of sliding contact line|
2, Take out the current collector and give power directly to the sliding contact line. If the circuit breaker doesn't trip, then there is no problem on the sliding contact line. Check the current collector.
3, If problem on sliding contact line is confirmed, divide it by every 60m, and check separately.
|Junction Box broken with water inside?||Change the Junction Box||Junction Box|
|Current Collector broken with water inside?||Change the current collector||Current Collector|
|Whether there is rubbish at the interior connection of the sliding contact line?||clear the rubbish by brush|
|Whether there is too much carbon powder or rubbish inside of the current collector?||Clear the carbon powder and rubbish inside of the current collector|
