What applications is HSC-7.5-2K2SA engineered for?

HSC-7.5-2K2SA 7.5 kVDC vacuum- and radiation-resistant parallel twin-circuit cable pairing an AWG 22 nickel-plated copper PEEK-insulated 7.5 kVDC coaxial unit with an AWG 22 PEEK LV return core under a common V2A stainless-steel wire braid. It is built to IEC 60544 / DIN VDE 0250 for ultra-high vacuum (uhv) chambers & surface physics and nuclear research, synchrotrons & beamline instrumentation.

What are the minimum bending radius and operating temperature range for HSC-7.5-2K2SA?

The minimum bending radius for HSC-7.5-2K2SA is 10 × OD across its continuous operating temperature range of -60 °C to +250 °C, ensuring mechanical and dielectric stability in industrial service.

How are the concentric layers of HSC-7.5-2K2SA arranged from inside to outside?

From inside to outside, the construction sequence is: (01) HV Unit (7.5 kVDC) (AWG 22 (19 x 0.16 mm) nickel-plated copper conductor, 7.5 kVDC PEEK dielectric, nickel-plated copper braid screen, and thin PEEK sub-jacket); (02) Parallel LV Unit (AWG 22 (19 x 0.16 mm, 0.38 mm²) nickel-plated copper low-voltage return/sense core with extruded PEEK insulation laid parallel to HV unit); (03) Outer Mechanical & EMC Braid (Overall V2A (AISI 304) stainless-steel wire braid enclosing the parallel twin assembly for ultra-high vacuum (UHV), radiation, and +250 °C service).

What factory test certificates are supplied with HSC-7.5-2K2SA?

Every production drum of HSC-7.5-2K2SA undergoes routine electrical continuity, high-voltage dielectric and dimensional testing per IEC 60544 / DIN VDE 0250, and is delivered with an EN 10204 3.1 factory test certificate.
