Core De tails
(1) The core details are as follows:
Conductors consist of 16 strands of 0.2 mm
diameter tinned copper wire.
Nominal cross-section area of conductor
= 0.5 mm
2
.
Nominal diameter of conductor = 0.93 mm
Nominal thickness of insulation = 0.45 mm
Minimum thickness of insulation = 0.40 mm
Minimum diameter of core = 1.75 mm
Maximum diameter of core = 1.90 mm
(2) Braided Screen
The cores are laid-up, covered with binding tape
over which is woven a braiding of 0.2 mm diameter
tinned copper wire.
(3) Outer Sheath
A PVC outer sheath is applied by extrusion over the
wire braiding.
(4) Maximum Current Rating
The maximum current ratings are as follows:
2.5 A at 1000 V dc
2.5 A at 440 V ac at 1600Hz.
