Specific property for usage of 110kv~220kv xlpe high-voltage cable
1. Cable's conductor highest working temperature is allowed up to 90⺠c, and overload when meet an emergency is 130⺠c, when short circuit (in � 5 seconds) the highest temperature is 250⺠c
2. When installing or laying cable, the ambient temperature should be less than -20⺠c, and have to give a preheat to cable.
3. The minimum bending diameter(in follow the table):
Note: in form, d0 is a real test value to cable's outer diameter.
4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) t=kã? core no. Ã? section (kg), in formula, the coefficient k value should be: the copper core get 7, the aluminum core get 4.
5. Allowed biggest lateral-press p, when cable is being bent
The single core cable is required pâ?¤ 500kg/m.
P=t/r (t is indicated axial traction force; r is indicated radius of bent-wheel), knowing from above formula, as the traction force is made up by length and weight of cable. So it lets p to applying requirement as above. Then the diameter of bent-wheel should be widened.
6. Cable laying is not being restricted by drop.
Application :-
These single core flexible cables are used for wiring in control panels, machines and various electrical installations In
small, medium and large industries.
Features :-
Manufactured from bright annealed 99.97% pure bare copper conductors, these cables have low conductor
resistance. These wires are insulated with a special grade PVC compound formulated and manufactured in-house
which is impervious to water, oil, grease, acids, etc. and are tough to protect from any mechanical abuses.
