HIGH TENSION CABLE
The high tension generator
and X-ray tube are two different assembly and are connected by a shock proof HT
cable. HT cable has three conductor wires, two for cathode and filament and one
for anode. In HT Cable, these three conductor wires are arranged parallel to
each other. These wires are made of copper metal and the insulator is insulated.
A flexible rubber
insulation sheath is fitted around these three wires. The thickness of this
rubber sheath is also increased as the voltage through the cable increases.
There is a flexible
metallic sheath around this rubber sheath. This metal plate is called Woven
mesh sheath. This metal sheet is connected to the earth. This metal sheet has a
cover made of cotton or plastic on the outside. It provides appearances and
mechanical protection to HT cable. One side of this metal sheet is attached to
the X-ray tube head and the other side is connected to the transformer tank.
Its connections are plug and socket type. If electrical or mechanical failure
of this cable occurs, then a smell like burning occurs.
