Medium, High and Extra High Voltage Cable Production
Upgrades

By utilizing reliable line components and avoiding pre-cross-linking in the extrusion process, you can achieve long cable production lengths. It is particularly true in subsea cable production, where minimizing the number of joints is essential.

While your compound suppliers provide clean XLPE insulation compounds, with our clean-run value package these compounds are kept clean. In fact, they are made even cleaner through the material conveying from the package to the extruder.

Optimal roundness is essential for efficient use of insulation material on a CV line. Cutting down material overuse is one of the biggest contributors to production productivity in pre-molded and pre-fabricated joints and terminations as well.

Roundness is a sum of many factors during the extrusion and cross-linking processes. Correct extrusion and cross-linking conditions can be achieved and controlled with correct equipment selection.

The cooling circulation of nitrogen shrinks the outer surface of the insulation, thereby forcing the insulated core into its round shape. This process enables a catenary line with moderate rotation to produce cables with thick walls.

It is possible to produce several medium voltage cores in the same run without stopping the continuous vulcanization line. This significantly reduces overall downtime, especially if the production contains frequent type changes. Continuous Type Change Value Package, which you can upgrade to without heavy investment, is an effective means to improve productivity.

Typical preheaters ineffectively heat conductors, causing the inner semicon material to penetrate the outermost wires. In a worst case scenario, the conductors can then no longer pass through the wire guide of the crosshead. Our Dual Preheating System uses two coils to effectively heat the entire conductor.

High and extra high voltage cables have important insulation thicknesses, and considerable insulation weight is supported by a small conductor. If the viscosity of the material close to the conductor decreases, as is the case when the temperature increases rapidly, significant drooping occurs and the insulation will be off-centered. In addition to eliminating the drooping effect, our patented method increases heating and cross-linking capacity, and thus line speeds, in catenary continuous vulcanizing lines for medium, high and extra high voltage cable production.
