| High Voltage Wire and Cable
The high voltage wire and cable specified in this catalog is used in a wide spectrum of industry:
- Travelling wave tubes, magnetrons and klystrons
- Laser systems: rangefinders, ring laser gyroscopes and night vision systems
- Cathode Ray Tubes (CRT)
- High energy physics research
- High voltage power supplies
Our customers are typically manufacturers of radar, ECM, laser and cockpit displays, satellite propulsion, missiles, medical, X-Ray equipment, ordnance systems and a wide range of other high voltage applications.
The minimum order quantity is small for any of the cables that are available from stock as we understand our customers requirements for prototyping and small production runs. Most of the cables can be supplied in continuous lengths up to 1580 meters, if required. Most of the cables are available in colours if required for identification purposes within the system .
High voltage wire and cable can be supplied in bulk form or specified as part of a cable assembly terminated to a Reynolds high voltage connector. Where possible we recommend that customers take advantage of Reynolds unique and reliable fabrication methods and quality oriented 100% production testing of cable assemblies under simulated aerospace environments.
Test Voltages
Most of the cables are tested at twice the operating voltage specified in the catalogue.
AC Voltages
Many of our cables are used in such applications but all of our cables are rafted at DC voltages and therefore for all pulsed applications we recommend that you evaluate and satisfy yourself that the cable meets your requirements.
Quality Control
Samples are taken from each cable reel and DC hi-pot tested in accordance with the test voltages quoted in our specifications. All operating voltages specified are applicable from sea level to 70,000 feet (21,000 meters) and -55 to +125°C.
Corona
The elimination of corona is critical to the life expectancy of any high voltage cable and any resultant cable assembly. FEP and PFA insulation contribute to good corona characteristics as the manufacturing methods ensure that voids are not present in the extruded insulation.
Operating Temperature Range
For FEP, PFA and silicone rubber wire and cable, we quote an operating temperature range of -55 to +125°C, which, although very conservative, is in line with the specified requirements of most military applications. The majority of our testing and history is based on this.
