Insulator Seal - Wires and Insulators

Wires and Insulators Introduction
ISI offers a wide range of coaxial cables, wires, rods and Insulators to compliment the electrical feedthrough products through this catalog. We offer many different solutions, from vacuum-ready Coaxial Cables to specialized wires, such as Kapton® Wire , for customized in-vacuum applications.


Coaxial Cables All Coaxial Cables are constructed with vacuum grade materials and components, including Stainless Steel braided shielding, high purity alumina ceramic insulation, Beryllium Copper contacts and Aluminum terminations. Cable assemblies are suitable for high temperatures and rated for high and ultra-high vacuum service. Please note that when connecting cables to feedthroughs, the effective voltage, current and temperature ratings for the set are reduced to that of its low rated component.

BNC Coaxial Cables / In-Vacuum ISI In-Vacuum connectivity solutions have expanded to include UHV compatible BNC coaxial cables. These cable assemblies can be baked to 250° C. The include general purpose "user end" terminations and two style of connectors designed to interface with ISI standard grounded and floating BNC feedthrough vacuum side terminations.

Wire, Rod and Tube ISI offers a wide variety of bare wire, rod and tube materials, all of which are suitable for high and ultra-high vacuum applications.Special purpose materials such as Stainless Steel braided shielding and Glidcop® Copper alloy wire, insulated with Fish Spline Ceramic Beads are ideal for the fabrication of vacuum ready Coaxial Cables and are particularly recommended for use in flexible coaxial cables. Also detailed in this section are thermocouple wire and rod materials. Wires are supplied as matched paires. Type C,R, and S are supplied in extension (compensating) grades only.

In-Vacuum Insulated Wire ISI in-vacuum Insulated wire is designed for high and ultrahigh vacuum use to 260° C. All conductors and shields are silver pleated copper wire. Insulation is Kapton® type F film which is applied and heat treated to effectively minimize trapped volumes of gas and maintain mechanical strength. KAP1, KAP2, KAP3 and KAP4 supplied in 10m (30-foot) rolls, KAP5 supplied in 5m (15-foot) rolls.

Insulator and Spacers All ISI standard Ceramic Insulator components are fabricated using high purity Alumina, 95% AL2O3, which is ideal for high and ultra-high vacuum service. Alumina is a multi-crystalline form of sapphire and its properties include high compressive and mechanical strength, high wear and heat resistance, good radiation resistance and high electrical resistivity. It also has a zero porosity and is hence impervious to all gases. All of these properties make Alumina an excellent engineering material suitable for some of the most extreme and demanding applications.

INTENDED OPERATING CONDITIONS
Electrical ratings are determined by various factors, including dielectric strength, geometry and system operating pressure. Please note that all ISI catalog products are electrically rated for operation with one side in dry atmospheric conditions and the other side in a vacuum environment with a maximum system
pressure of 1 x 10^-4 Torr. We advise that users make allowances for deviations from stated operating parameters and take adequate safety precautions when feedthroughs are operated at high voltages or high currents.
