14 Series High-Voltage Connectors
A compact high-voltage cable assembly platform designed for systems requiring controlled electric field geometry, stable insulation performance, and repeatable termination integrity — operating up to 50 kV DC.
14 Series — additional views
Built for compact, electrically stable single-conductor HV interfaces
The 14 Series platform was developed to provide a compact, electrically stable single-conductor high-voltage interface for instrumentation, power supply, and test systems where reliable insulation and predictable electrical behavior are critical. Each assembly integrates a molded Caton connector interface with engineered cable insulation systems to maintain reliable electrical performance across the operating range.
The 14 Series is the right choice when you need a compact, push-pull interface for a single high-voltage conductor — particularly in scientific instrumentation and test equipment where space is constrained and consistent electrical behavior is required.
Typical capability
| Parameter | Typical Capability |
|---|---|
| Operating voltage | Up to 50 kV DC |
| Dielectric withstand | Configuration dependent |
| Corona / partial discharge | Not rated — performance dependent on system configuration and operating conditions |
| Current rating | 10 A |
Electrical capability varies depending on conductor selection, insulation architecture, and operating environment.
Insulation architecture
| Element | Description |
|---|---|
| Primary insulation | Silicone rubber per A-A-59588 |
| Shielding | Not available on 14 Series |
| Field grading | Combination of molded geometry and tapered conical interface that controls electric field stress and eliminates air gaps at the mating interface |
| Termination insulation | Overmolded silicone structure forming the termination insulation system |
| Interface control | Tapered mating geometry designed to displace air and create a continuous dielectric path between plug and receptacle |
When mated, the conical interface displaces air and forms a continuous solid dielectric path between plug and receptacle — eliminating air gaps that could otherwise support corona inception or partial discharge.
Operating environment
| Parameter | Rating |
|---|---|
| Operating temperature | -55 to +125°C |
| Altitude capability | Rated values maintained to 70,000 ft |
| Chemical exposure | Application dependent — material compatibility based on insulation system |
| Humidity | Application dependent |
| IP rating | Not specified |
Assembly arrangements
The 14 Series is available in multiple voltage classes and assembly arrangements, allowing integration into a range of high-voltage platforms.
How the 14 Series manages HV assembly risk
High-voltage cable assembly performance depends on maintaining controlled electric field distribution throughout the connector interface and termination region. The 14 Series architecture is specifically designed to prevent the most common failure modes.
Air gaps at connector interfaces create field concentration points that can initiate corona under operating voltage.
Tapered conical interface displaces air and forms a continuous dielectric path — eliminating the gaps where corona initiates.
Partial discharge degrades insulation progressively — often without early warning — leading to premature failure.
Molded insulation geometry controls electric field stress distribution throughout the connector interface and termination region.
Uncontrolled termination geometry creates localized field stress that accelerates insulation breakdown over time.
Overmolded silicone termination structure provides controlled geometry and a continuous insulation system at every termination point.
Working directly with system designers
Caton engineers work directly with system designers to evaluate connector interfaces, cable insulation systems, and termination structures — ensuring the assembly performs reliably under real operating conditions. Because Caton manufactures both the cable assembly and connector interface, our team can evaluate the complete high-voltage interconnect system rather than individual components.
