Water cooled high current cables

with solderless pressed cable heads preferably for mains frequency

water cooled cables in standard design

Construction and application

Single conductor cables manufactured in the cross-section ranges up to 1000 mm² and up 1200 mm² as multiple conductor cables. Ideally suited for mains frequency applications, e.g. in production plants in the steel foundry, non-ferrous metal or glass melting industries, but applications are also feasible in graphitizing furnaces. Our cables are used wherever high currents are transmitted with relocatable loads or in adverse deployment conditions in heating operations. As a result of the construction selected for the inside conductor, combined with the special coolant water hoses and our manufacturing technology, we offer extremely flexible space-saving components for high current transmission.

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 connection holes / hose nipples

Thread holes of a sufficient size are made in the connectors to hold hose nipples. The cable is delivered without nipples as standard. These can be additionally ordered as accessories according to our catalogue page 50. It is also possible to set the cooling holes at other orientations than the standard or to change the thread size.

Cable with additional shimes

To ensure secure fixture, especially in the case of long water cooled high-current cables, all single conductor cables ca be fitted with one or more shims. These additional solid parts fitted in the conductor guarantee easy fitting at the labelled points by means of clamping or holding devices. Squeezing the hose together and the ensuing damage, as well as the reduction in water flow through put, are thereby avoided.

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 flame retardant and self-extinguishing. The breakdown rating is 6 kV/mm. The maximum allowed operating pressure for the cables is 6 bar. All cables are tested with a pressure of 10 bar before leaving our factory.

Special designs and cable repairs

In addition to our standard designs, we also manufacture all cable cross-sections with connectors, as well as offering customised designs ( e.g. replacement parts for all common electro-furnaces from the well-known manufacturers). We also undertake cable repairs at short notice, both for our cables and those of other manufacturers.
