Power cables

Winding up to extra-high voltage The fully automatic PS 200/8 Combo fromPS Costruzioni Meccaniche is capable of wind- ing power cable onto either coils or spools, reducing customer investment – a single line can produce two different products. PS’s design engineers have also paid particular attention to improving the shape of the final product.

Coil technical details : Outer diameter, 95mm, 230mm Interchangeable internal core, 70mm, 115mm Height, 35mm, 114mm Spool technical details Flange diameter, 120mm, 230mm Barrel diameter, 40mm, 109mm Overall width, 42mm, 114 mm Bore, 35mm, 104mm Min. internal flange width, 35mm, 105mm PS Costruzioni Meccaniche Srl – Italy Fax : +39 03968 98769 Email : ps@pscostruzioni.com Website : www.pscostruzioni.com

PS 200/8 Combo can handle the following range of cables: Cable type & diameter : Insulated flexible cables, 2mm, 10mm Solid insulated wires, 2mm, 5mm Multicore flexible cables, 2.5mm, 10mm Flat cables, 5.5 x 3.5mm, 13 x 5.5mm Type of production : Coil/spool according to the cable diameter, 5 metres, 100 metres

Rigid strander for MV to HV power cable This rigid stranding line from C M Caballe has been redesigned and upgraded in collaboration with energy cable manufacturers, to include the following improvements: A pintle operated by a motoreducer for perfect holding of the bobbins, even • with different widths. It requires less maintenance than a typical pneumatically operated pintle Accurate wire tension control by specially designed spring-free pneumatic brakes • Fully automatic loading system that reloads the complete line in 12 minutes • Self-centring rollers and compacting heads for Milliken conductors •

Cleaning extruding equipment

In extensively automated working pro- cesses, such as the extrusion of cables, the only possibility to reduce costs is to reduce scrap, energy usage and machine downtime, and to extend the lifetime of tools and machine parts such as extruder screws. The use of effective cleaning technology can help to achieve the optimisation of costs. Machinery –Technology – Trading GmbH (MTT) has developed a wide range of equipment for the cleaning of extruder screws, machine parts, extrusion tooling and crossheads using micropeening technology. Micropeening is a dry cleaning process. A defined blasting agent is shot by compressed air, at room temperature, onto the surface of the part to be cleaned. The blasting agent consists of thermo- set polymer and can be described as working like many tiny chisels, so that all thermoplastic, duroplastic and elastomer particles are removed by a mechanical process – without heating and solvents, and without damage to even highly polished surfaces. The blasting agent has no negative effects on the cleaned surface of the parts, in contrast to the standard cleaning methods (burning, scarping, brushing and solvents) and increases the lifetime of parts.

Rigid cage, 44 bobbins 560mm, for screening MV and HV cable ▲ ▲

A range of accessories allows the manufacture of the following products: Compacted conductors of copper and aluminium for LV, MV and HV insulated • conductors Sector conductors (Milliken) of copper and aluminium for HV insulated conductors • Aluminium (AAAC, ACSR,) aerial conductors with round or trapezoidal wires • Screening with copper wires (single or multi-wire) for MV and HV conductors • Armouring with galvanized steel wires •
