Krempel has a large pool of textile machines to weave, braid and knit woven tapes, insulation sleevings and cords. These textile products are required for electrical machines and transformers.
Insulating sleevings, woven tapes and tying cords are braided, knitted or woven from glass, polyester or blended yarns and extruded from silicone elastomers. Fibre-based sleevings can be additionally impregnated or coated with silicone, acrylic or polyurethane resins.
Glass or polyester fillings are possible. The quality of the hoses complies with BS, IEC, ASTM and NEMA standards. Various types are also CSA or UL approved.
VIDAFLEX Insulation Sleevings
VIDAFLEX insulating sleevings can either be extruded from silicone elastomer compounds or braided/knitted using glass or polyester yarns. The fibre based sleevings are then impregnated or coated with a range of silicone or acrylics resins to provide varying thermal and electrical properties tailored to specific customer applications.
Excellent protection against electrical, thermal and mechanical stresses is provided for cables, strands and conductors depending on the type of VIDAFLEX insulation sleeving used. The quality grades available for VIDAFLEX meet BS, IEC, ASTM and NEMA standards, several types are also CSA and UL recognised and are compliant to the directive 2011/65EU (RoHS).
Thermal classifications covered are 155°C, 180°C, 200°C & 220°C. Untreated glass fibre products are also available which will exceed these thermal classifications.
VIDATAPE Sealing Tapes
VIDATAPE woven tapes are made from either glass or polyester yarns as well as from combinations of different yarn types, e.g. glass/polyester, glass/aramid or glass/copper wire. Special variants: Tapes made using pre-shrunk or high-shrinkage polyester yarns.
VIDATAPE woven tapes are used for a variety of banding applications in the electrical machine construction and for producing transformers.
VIDACORD Tying Cords
VIDACORD and KREM.cord tying cords are glass and/or polyester-braided or knitted tying cords which can have a glass or polyester fibre filler. The outer sleeve construction depends on the requirements - for easier handling, for example, a polyester- braided outer with a glass filler is preferred.
