Medium, high and extra high voltage cable production line upgrades

Are you looking for minimum operation costs? Our applications for MV, HV and EHV cable production meet the tightest demands for quality and performance.

Long run value package >>>
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.

Clean run value package >>>
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.

Round value package premium >>>
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.

Round value package standard >>>
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.

Round value package basic >>>
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.

Continuous type change value package for MV CCV lines >>>
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.

High output value package for MV CCV lines >>>
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 output value package for HV/EHV CCV lines >>>
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.

Quick conductor splicing value package for MV CV lines >>>
Our Quick Conductor Splicing Value Package allows quick conductor splicing for compact round stranded medium voltage (MV) conductors up to 800 mm².

Quick conductor splicing value package for HV/EHV CV lines >>>
Our Quick Conductor Splicing Value Package allows quick conductor splicing for compact round stranded medium voltage (MV) conductors and high voltage (HV) Milliken conductors up to 3000 mm².

High output screw value package >>>
New screw design leads to higher output for your extruder.

Component upgrades
Line control automation upgrade >>>
Your line risks a complete shut down because of obsolete line control technology. Don't keep your customers waiting and let your reputation suffer.

Process supervisor unit hardware upgrade >>>
Obsolete process supervision technology is putting your line at risk of a complete shut down. Don't keep your customers waiting and let your reputation suffer.

Human-machine interface upgrade >>>
Obsolete human-machine interface technology is putting your line at risk of a complete shut down. Don't keep your customers waiting and let your reputation suffer.

Caterpillar & capstan drive & motor upgrade >>>
Your caterpillar or capstan may be stopped because of an obsolete drive or motor. Don't keep your customers waiting and let your reputation suffer. Have your process requirements changed; do you need more speed or more pulling force from the equipment?

Accumulator PLC, drive & motor upgrade >>>
The accumulator is not working because of an obsolete PLC, drive or motor. Don't keep your customers waiting and let your reputation suffer. Have your process requirements changed; do you need more capacity in the equipment?

Extruder drive & motor upgrade >>>
Has your extruder come to a halt because of an obsolete drive or motor? Don't keep your customers waiting and let your reputation suffer. Have your process requirements changed; do you process different materials which require different performance?

Extruder cooling upgrade >>>
Do you want to increase the extruder reliability and improve the process performance of your water cooled extruder?

Extruder screw & breaker plate upgrade >>>
Want to optimize the output for process demand and improve the process performance of your semicon and insulation extruders?

Crosshead tempering unit upgrade >>>
Want to improve the temperature stability in the triple crosshead and in the insulation extruder screw cooling circulation?

Nitrogen blower upgrade >>>
Want to save your maintenance and nitrogen consumption costs due to the leakage in your nitrogen blower which requires line stop and sealing replacement?

End seal upgrade >>>
Want to make longer production runs and save nitrogen costs?

Single Pay-off & Take-up drive, motor & gearbox upgrade >>>
Your single Pay-off and Take-up may be down because of an obsolete drive, motor or gear box. Don't keep your customers waiting and let your reputation suffer. Have your process requirements changed; do you need another type of reel, more pulling force or more speed from the equipment?
