Water-Cooled Cable Product Introduction
1. Product Overview
Water-cooled cable is the core conductive connecting component for
submerged arc furnaces, ferroalloy furnaces, industrial silicon
furnaces, calcium carbide furnaces, refining furnaces and various
high-current metallurgical electric furnaces. It undertakes the
transmission of large current between short net, electrode holder
and transformer secondary side.
Conventional bare copper cables generate severe heat under high
current, leading to temperature rise, large power loss, easy aging
and frequent replacement. Our water-cooled cable adopts internal
circulating water cooling structure, which rapidly takes away joule
heat generated during current transmission. It features low
temperature rise, low resistance loss, stable conductive
performance and long service life. It is widely matched with
6300kVA–63000kVA full range of metallurgical electric furnaces, and
is an essential part of furnace short network energy-saving
transformation.

3. Core Structure & Working Principle
The whole cable is composed of four core parts: conductive braided
copper body, cooling water circulation channel, insulating
protective layer and metal connection terminal.
- Conductive Braided Copper Conductor
Made of high-purity oxygen-free copper wire with high conductivity,
dense braided structure ensures excellent flexibility and large
current carrying capacity, effectively reducing contact resistance. - Circulating Cooling Water Channel
Cooling water flows through the inner pipeline in closed
circulation, continuously absorbing heat generated by copper
conductor during power transmission, keeping the cable operating at
low temperature. - Multi-Layer Insulation & Protective Jacket
High temperature resistant, aging resistant and insulating rubber /
stainless steel corrugated outer layer, isolating high temperature
radiation, molten iron splash and mechanical abrasion, avoiding
short circuit and leakage risks. - Integrated Welded Terminal Flange
Both ends adopt integral copper flange structure, seamless welding
with copper braid, uniform current distribution, small contact
resistance, equipped with water inlet and outlet interfaces for
quick connection of circulating water pipeline.
4. Main Product Advantages
4.1 Low Power Consumption & Energy Saving
Circulating water cooling effectively controls cable temperature
rise, greatly reduces resistance heat loss, lowers transformer
load, cuts smelting power consumption, and brings obvious
energy-saving benefits for long-term production.
4.2 High Safety & Long Service Life
Low operating temperature slows down insulation aging; anti-spatter
outer structure prevents molten metal burn-through. No overheating
burnout failure under long-term full-load operation, greatly
reducing shutdown maintenance frequency.
4.3 Excellent Flexibility & Convenient Layout
Multi-spec flexible braided design adapts to electrode lifting,
furnace body expansion and contraction, various complex short net
layout; light weight, easy installation, disassembly and
replacement.
4.4 Stable Current Transmission & Uniform Melting
Low and stable overall resistance ensures balanced current of each
electrode, avoids partial overheating of furnace charge, stabilizes
furnace condition, reduces product composition fluctuation and
improves finished product yield.
4.5 Customized Matching & Strong Adaptability
Customizable parameters including cable length, cross-sectional
area, bending radius, flange size, water channel quantity, outer
protective structure according to furnace current, short net space
and cooling water pressure. Suitable for new furnace supporting and
old furnace energy-saving renovation.
