Okonite X-Ray cables are suitable for use on X-Ray apparatus for medical, industrial, research and control applications. They give trouble-free
performance where pulse type high voltages are required. Although primarily used with medical diagnostic imaging equipment, Okonite
X-Ray cables are also used with equipment in industrial applications as well as in research projects where high voltages, low power are
Typically, Okonite X-Ray cables are used to supply the anode and cathode voltages to the X-Ray tube. Since one terminal operates at a negative
potential and the other at a positive potential, the voltage across the X-Ray tube is twice (2X) the rated voltage of the cable.
The two usual constructions are (1) three conductor (3/C) used on typical cathode cable installations, and (2) four conductor (4/C)
utilized on installations with a grid controlled lead. Upon request, designs and constructions can be developed for special applications.
- Performance tested for long trouble-free service.
- Small diameter.
- Flexible construction.
- Excellent flexing endurance.
- Mechanically rugged.
- Easy to strip and terminate.
- Resistant to most oils and chemicals.
- Complies with NEMA Standard XR-7 where applicable.
The minimum bending radius for permanent installation or flexing in service is four times
the cable diameter.
Cable Core: Each cable contains two #15 AWG (19x) [1.65mm2] tinned copper filament wires insulated with heat sealed color coded polyester
tape. Three conductor cores include two uninsulated #18 AWG [0.83mm2] flex stranded tinned copper wires. Four conductor cables include one
#20 AWG (7x) [0.52mm2] copperweld conductor per ASTM - 45 insulated with heat sealed polyester and shielded with metalized red polyester.
The four conductor core includes three uninsulated #18 AWG flex stranded tinned copper wires.
All conductors are twisted together into a composite assembly.
Core Shield: An extruded layer of semiconducting compound encapsulates
the composite core assembly.
Insulation: Okonites premium high voltage EPR (ethylene propylene
rubber) insulation is extruded in tandem with the semiconducting compound ensuring an intimate contaminant free bond between the layers
Shield: A semiconducting tape is applied over the insulation with
a tinned copper wire braid. Minimum coverage indicated in table.
Jacket: A light gray flexible Okoseal (specially compounded PVC)
jacket is extruded over the shield to provide additional mechanical strength and resistance to most oils and
