Component Specifications

Definition
A conductor/penetrator is a specialized feedthrough component designed to allow electrical conductors (wires, cables, or busbars) to pass through pressure vessels, vacuum chambers, or containment barriers while maintaining hermetic seals, electrical insulation, and mechanical integrity. It serves as an interface between different environmental conditions while preventing fluid/gas leakage and maintaining electrical continuity.
Working Principle
The conductor/penetrator operates by using insulating materials (ceramics, glass, or polymers) to electrically isolate conductive elements from the mounting structure while creating a permanent seal through brazing, welding, or compression. The conductor passes through the insulator, which is bonded to both the conductor and the barrier wall, creating a leak-tight path that withstands pressure differentials, temperature variations, and chemical exposure.
Materials
Conductor: Oxygen-free copper (C10100/C10200), aluminum (6061-T6), or nickel-plated materials. Insulator: Alumina ceramic (Al2O3 94-99.5%), glass (borosilicate), or high-performance polymers (PEEK, PTFE). Sealing: Active brazing alloys (ABA), glass-to-metal seals, or elastomeric gaskets (Viton, EPDM).
Technical Parameters
  • Leak Rate <1×10^-9 mbar·L/s

Frequently Asked Questions

What is the difference between a conductor and a penetrator?

In this context, 'conductor' refers to the electrical carrying element, while 'penetrator' describes the complete assembly that allows penetration through barriers. The terms are often used interchangeably for feedthrough components.

How are conductor/penetrators tested for leaks?

They undergo helium leak testing per ISO 20485 standards, with typical acceptance criteria below 1×10^-9 mbar·L/s for high-vacuum applications.

Can conductor/penetrators be customized for specific applications?

Yes, they are often custom-engineered for voltage/current requirements, pressure differentials, temperature ranges, and chemical compatibility with process environments.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
