B.Voltage Test
Each drum of finished cable should withstand power frequency voltage 3.5kV for 5 minutes.the insulation is not breakdown.
C.Test on bunched Cable Under fire conditions.
(1).Category of Sample
The number of cable lengths required to give a total volume of combustible materical per meter of:
Category A:7 Liters
Category B:3.5 Liters
Category C:1.5 Liters
(2).Duration of application of the flame
In the case of cables samples in Category A and B the test flame should be applied for 40 min,
Cable samples in Category C should have the test flame applied for 20 min.
(3).Evaluation
After burning has ceased,the charred portion of cable should not have reached a height exceeding 2.5m
- Service Conditions and Parameters of Cable
The cable is applied to fixed installation for rated voltage 0.6/1kV of power transportation and distribution line.
Max. Rated Temperature of conductor:Nominal Operating 90oC
Short Circuit:(Max. for 5 Sec.)250 oC
Temperature of laying,in air 25 oC
Under ground 15 oC
For laying,single core,triangle laying for three cables.
Depth of laying in direct:100 oC
Coefficient of thermal resistivity of soil 100 oC.cm/w
The cable can be laid without drop restriction,and the environment temperature shall not be lower than 0 oC.
Single core,steel tape armoured cable should be only aplied to DC line.
For nominal insulation thickness,size of armour,over all diameter,weight and current rating of retardant-flame cable of class A,B,C,you should refer to the value of general cable.
