Electric Cable (VV22)

タイトルまたは説明

(.1) Rated voltage Uo/LT is 0.6/1 kV.
(2) Maximum rated temperature of cable conductor is *0 0C
(3) Maximum conductor temperature is lower than ***0C when cable is shorted for less than 5 seconds.
(4) Ambient temperature is not lower than 0 0C and its minimum bending radius is as follows when cables is installed:
For single-core cable **0 (D+d),
Unit:Millimeter
For multi-core cable*5 (D+d),
Unit:Millimeter

The main technical parameters
.Calculation condition of capacity
.Ambient temperature is *5 0C
.Conductor working temperature is *0 0C
.When the cable is laid underground, the coefficient of soil heat resistance is g=1.0 0C m/W without considering the phe- nomenon of increased coefficient of soil heat resistance caused by moisture over in a long-term operation of cable.
.Gap between axis of cable and surface of ground is ***0 millimeter when is is laid in ground
.For mulit-core cable, gap of axis of cables is 3 times O.D.
