The manufacture of power cables includes many processes and can be generally divided into four main areas:
Conductor manufacturing, including 1) Drawing a wire to a desired diameter;
2) Stranding strands of multiple strands, sometimes requiring re-entrainment;
3) Combination in the manufacture of HV and EHV cables, stranding non-circular strands into a quasi-circular structure;
Insulated core manufacturing, including 1) Three-layer extrusion: Insulated cable cores are formed during this process, including the inner semi-conductive shield, the insulating layer and the outer semi-conductive shield;
2) Cross-linking: can be carried out directly after extrusion (peroxide cross-linking), or after extrusion using separate equipment (wet cross-linking);
3) Degassing: Removal of peroxide by-products by off-line heating, which is usually the basic process for HV or EHV cables, but is also often used for medium voltage submarine cables;
Cable sheath manufacturing, including 1) insulated wire core tape: In this process, the buffer layer, protective layer and water blocking layer are wrapped around the extruded insulation core;
2) Neutral wire stranding: Wrap the copper wire, copper tape or flat copper tape around the cable;
3) Metal sheath: moisture-proof and protective layer of metal;
4) Sheath: The use of a polymer sheath for mechanical protection (protection of metal foil is particularly important) and anti-corrosion effect;
5) Mounting: Use high-strength metal components (steel) to protect cables, especially submarine cables;
Quality control, including 1) raw material handling;
2) routine tests;
3) sampling test;
Vegetable Peeling, cutting, cleaning, drying, sorting, and packing a wide variety of vegetables, leafy greens, and fruits is a breeze with our fresh cut processing lines. Whether you are a catering business, a restaurant chain, a fast-food chain, or a food processing business, our fresh cut fruit and Vegetable Processing lines are ideally suited for you. Our food-grade equipment are entirely manufactured in the Netherlands and adhere to the strictest fruit and vegetable processing hygiene standards. With our fresh cut lines, a wide variety of products can be produced for export or sale in local supermarkets. Some examples include ready-to-eat products such as leafy greens or mixed salads in pillow bags, as well as fresh cut French fries in vacuum sealed bags. Furthermore, the cut vegetables can be processed further and sold as frozen products or canned goods. Not to mention, it is possible to prepare ready-to-eat fruit salads and fruit cups as convenient, highly nutritious snacks.
Our vegetable processing machines have a flexible design that enables them to function perfectly well alone or as part of a complete line. This smart design also makes it possible for you to start with a small semi-automatic Vegetable Processing Line.
