Main components
Cable Reel
Reel size and type basis cable length and customer needs design, the type can be made into rolls disc or roll, surface spray marine anticorrosive paint.
High-voltage slip ring (maximum capacity)
JL-HVSR- 650A 10kV
Rated voltage: 6.0kV,6.6kV, 10kV,
Rated frequency: 50/60Hz
Rated current: 650A
Rated capacity: 7.2MVA
Frequency converters
Control the forward rotation of the motor by means of a frequency converter, Reversal and rotational speed. Implement the cable's Control of retracting, releasing and speed
Motor+hysteresis coupling
Motor: Used to control the forward and reverse rotation of the reel.
Hysteresis coupling:Under normal circumstances,the speed of the motor is transmitted to the reducer.
When the rear end is stalled, it slips to prevent overloading the motor. When the motor does not work properly or the cable receives a pull force greater than the set value, the reel cable can be released to prevent the cable from being damaged by excessive force pulling off.
Reducer
Reduce the output speed and increase the output torque to meet the rear end equipment there is enough torque to turn.
Remote Control
Wired remote control; Wireless remote control. The ope rator can remotely operate the cable frame, from the side of the boat and cable retraction/discharge. It also has an emergency stop button.
Cable rack
It is divided into hydraulic type and hand-cranked type.
Function: Cable transfer to the outboard of the ship, with multi-roller, to prevent friction damage between
the cable and the broadside, the structural design meets the requirements the bend radius of the cable is req uired. When mooring, it is low ered to the side of the ship outside, not in use or retracted when sailing.
Depending on the design requirements, a set of tension transmitters can be installed on the front end sensor,monitors the tension received by the cable and is analog is transmitted to the PLC, and the tersion value has been displayed.
Pulse counter
Through a certain transformation ratio, the rotation of the reel is monitored in real time number, sent to the PLC in analog form to convert to cable receipt the length value returned or streamed.
At the same time, 3 levels can be set Bits: full, last 2 laps, last lap, and open off output.
Control box
The control box is floor-mounted. Made of 316L stainless steel plate made, thickness 3mm. For the front door panel, left and right large sides the sealing plate and other parts of the shell that are welded are used in the table surface electrostatic spraying process to ensure its corrosion resistance and shape beautiful, the hole of the incoming and outgoing cable should be installed with a waterproof connector.
1) Electricity : AC400V/450V, 50/60Hz
2) Rated power: 4-7.5KW.
Control box internal equipment
Inside, touch screen all-in-one, button, indicator light, frequency converter, control transformer, micro-fault, control transformer, select devices such as switches. The main components are all XimenSub, Schneider and other w ell-known brands
