Medical cable

4-wire

Short Description
High-voltage cable designed for DC high-voltage connections between X‑ray tubes and generators. Suitable for medical and industrial X‑ray systems (mobile/portable X‑ray, DR, CT, C‑arm, angiography) and low-power high-voltage test equipment. Available in straight and elbow connector versions.

Features

• Compatible with DC high-voltage X‑ray systems (medical and industrial NDT, DR, CT).
• Variants: 75 kV for tube voltages < 150 kV; 90 kV for tube voltages up to 150 kV and for moving applications.
• Connects X‑ray tube to high-voltage generator.
• Connector styles: straight or elbow.
• Custom cable lengths and separate cable accessories available on request.
• Minimum bending radius in service should not be less than 66 mm.

Usage / Usage scenario
Cable sheath must be smooth and uniform with no joints, bubbles or bumps. Weave shield density ≥ 90%. Minimum insulation and sheath thickness ≥ 85% of nominal. Insulation between core and insulated wire and between core and ground withstands AC 1.5 kV for 10 minutes without breakdown. Insulation between core and shield withstands DC 90 kV for 15 minutes without breakdown. Plug body withstands repeated drop tests (≥ 1000 falls) without damage. DC resistance of conductor and ground cable ≤ 11.4 ± 5% Ω/m. Core insulation resistance ≥ 1000 MΩ·km. Cable and components comply with RoHS 3.0 and REACH requirements.
