GH Group companies

Companies that benefit directly from GH induction heating technology are:

•Manufacturers of cable for power transmission and distribution, offering their final customers high quality cables and increasing their output, only by upgrading the existing production line integrating GH systems.

•Manufacturers of complete systems or extrusion lines for energy cable production, offering their customers a high-production and versatile line; superior process technology; and full control of the process based on temperature or speed.

BENEFIT GH INDUCTION SOLUTION FEATURE

Integration

Same benefits in either existing lines or new production lines Engineering services for designing and installation

Communication interfaces for centralized management

Production

Increase of cable outputFast and direct heating of the conductor or metal

Control of cable temperature

Production of new cable types with minimum investment GH Inductor shop can develop any type of inductor optimizing its usage.

In pre-heating, the “One-coil” feature uses a single inductor for a range of cable diameters.

Cable quality

Homogeneous meltTemperature and process control. The “Heating pattern” feature controls the process according to temperature or line speed

Secure insulation adherence

Scratch-free and smooth surface

Operation & Maintenance

Control of the process Application and generator management system

Low maintenance system Tough equipment with huge life span

Environmentally-friendly Non-flammable, no toxic gases, no combustion

The cable manufacturing industry involves many different processes.

The optimal distribution of heating induction processes contributes to the advantage of producing outstanding quality products and high outputs in cable lines. The insulation and sheathing processes of high and medium voltage power cables, submarine cables, mining cables and other uses for energy cables are a perfect example of procedures in which induction heating provides extraordinary benefits.

Induction heating is a proven technology that is widely known in the cable industry. The main customer benefits of GH induction heating solution are:

GH turnkey solution

Developed solutions for specific customer needs

Specific project needs can be successfully implemented thanks to GH experience, know-how and the resources available for every customer:

•In-line and off-line solutions design and manufacturing. Mechanical, electrical and control engineering allow designs to be integrated in automated production lines or standalone systems fully adapted to customer requirements.

•Application development service and laboratory test for evaluating induction application technical viability and developing specific processes.

•Induction power systems and inductor shop covering the whole range of frequency and power requirements in cable processes up to 400 kHz and 2000 kW.

•Customer services for installing, commissioning, training and maintaining the system during its whole production life.

In-line cable pre-heating before extrusion

For copper and aluminium conductors

•Better insulation adherence increasing the cable output up to 20% in vertical and horizontal lines

•Uniform insulation melt

•Easy integration and optimal dimension of GH system

Off-line & in-line mould pre-heating

•Instantaneous heating that allows the moulds to reach a certain temperature in a shorter time

•The off-line system cuts down production time due to moulds already being pre-heated when they are placed in the line.

Wire heating before aluminium injection

In-line aluminium sheathing

•The most efficient heating to bond the aluminium foil

•Cable pre-heating for another extrusion phase

•Compact solution

In-line cable post-heating after extrusion

For copper and aluminium conductors

•The uniform heat from inside the cable allows to the manufacturer to choose between:

•Reducing the vulcanization tube length

•Increasing the line speed

•Customized system integration
