| Following are the key parameters to consider when selecting high voltage connectors and for cable assemblies from this catalog: |
| DC Voltage Rating |
|
All the connectors, cable assemblies and cable presented in this catalog have a recommended steady state DC voltage rating. The voltage ratings are based on a number of critical factors:
- Thickness of the dielectric material between the contact(s) and the shell.
- Type of dielectric material.
- Length of the sealed surfaces at the connector interface.
- Geometry of the contacts and cable.
- Amount of partial discharge present.
There are two mechanisms for dielectric failure in a cable assembly: Thermal degradation and gradual degradation of the material by partial discharge. If a cable assembly operates below the voltage that sustains partial discharge, then only the connector insulation components need to be considered in the cable assembly design.
As a quality control procedure, each of Reynolds products are, as a minimum, subjected to a dielectric strength test. The purpose of this test is to subject the connector or cable assembly to a voltage greater than the designed operating voltage. The dielectric strength test values used at Reynolds are shown below:
| DC RATING |
TEST VOLTAGE |
| 0 to 12 KVDC |
150% of rated voltage |
| 12.1 to 20.0 KVDC |
140% of rated voltage |
| 20.1 to 30.0 KVDC |
130% of rated voltage |
| 30.1 KVDC and up |
120% of rated voltage |
|
| Current |
|
The steady state current rating depends on conductor material, cross-sectional area, thermal capability and resistivity of the insulation and the proximity of other conductors.
|
| Temperature |
|
| The storage, transient and operating temperatures need to be specified in order to select the correct insulation material. |
