Water cooled high current cables

with solderless pressed cable heads preferably for electric arc- and ladle furnaces

Cables in standard design
up to conductor cross-section of 6000 mm²

Special coolant water hose
with traffic light effect as early warning system

Construction and application

Manufactured out of several flexible, stranded copper ropes with a cross-section range of 400 mm² or 500 mm² wounded around a supporting tube. We use stranded ropes in special construction and every second single conductor rope is protected against abrasion with a perforated hose. The wire-Ø and the construction of the ropes are so selected that the mechanical wear is minimized. Preferably such cables are used inside of electric arc- and ladle furnaces.

Connectors and cooling

All standard connectors/cable heads are manufactured out of E-copper material and are crimped on the E-copper conductor without soldering. Using our druseidt crimping technology, only materials of the same conductance value are connected together, without the use of additional materials, such as solder or welding additives. This ensures the best possible loss-free current transmission. The geometry and positioning of crimping facilitates the best possible coolant water flow.

Coolant water connections holes/hose nipples

Thread holes of a sufficient size are made in front of the cable heads to hold hose nipples or tubing connectors. To realize an optimal cooling process we equip the cable heads with one separate borehole per single conductor rope. The position of the drilling is so selected that an optimized water flow is guaranteed. The cable is delivered without nipples as standard. These can be additionally ordered as accessories e.g. according to our catalogue page 50.

Coolant water hoses

The flexible coolant water hoses we use are fitted with additional heat protection against radiated heat and liquid metal splashing. The hose casing is non flammable and self extinguishing. In standard design we use a high quality tube, non conductive, with excellent physical properties and extremely resistance to abrasion. To control the wear and the abrasion the tube is equipped with a so called traffic-light effect, which based on the green respectively red rubber layer inside of the hose casing. So it is possible to control the tube condition optically. The latest moment for changing and repairing the cables should be given when the red rubber layer is visible.

Allowed working pressure : max 6 bar
Testing pressure : 10 bar
Current load : As approximate value we recommend circa 4,5 A/mm²
