What governing standard and construction define OFC-HC Hollow Water-Cooled Conductor (Oxygen-Free Copper (Cu-OFE) Hollow Water-Cooled Magnet Conductor Profile)?

OFC-HC Hollow Water-Cooled Conductor (Oxygen-Free Copper (Cu-OFE) Hollow Water-Cooled Magnet Conductor Profile) is manufactured in accordance with EN 13605 / ASTM B152 (Cu-OFE CW009A) for Up to 10 kV service over -40 °C to +150 °C. Its 2-layer construction comprises internal deionized-water cooling channel, oxygen-free electronic copper (cu-ofe cw009a) body.

What is the minimum bending radius and installation temperature for OFC-HC Hollow Water-Cooled Conductor?

The minimum installed bending radius for OFC-HC Hollow Water-Cooled Conductor is 8 × OD across its continuous operating temperature range of -40 °C to +150 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of OFC-HC Hollow Water-Cooled Conductor arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Internal deionized-water cooling channel (Seamless precision-extruded circular or rectangular coolant bore for direct heat removal); (02) Oxygen-Free Electronic Copper (Cu-OFE CW009A) body (≥ 99.99 % pure Cu-OFE (≥ 101 % IACS) hollow magnet conductor profile per EN 13605).

What factory test certificates are supplied with OFC-HC Hollow Water-Cooled Conductor?

Every production drum or spool of OFC-HC Hollow Water-Cooled Conductor undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per EN 13605 / ASTM B152 (Cu-OFE CW009A), and is delivered with an EN 10204 3.1 factory test certificate.
