The experience of one century 百年经验 2 Röchling Engineering Plastics
Ein Jahrhundert Erfahrung The experience of one century For almost one century Röchling Engineering Plastics KG has been manufacturing the insulation material Lignostone Transformerwood for use in oil filled transformers. This outstanding material enjoys an excellent reputation within the international transformer industry. What is special about Lignostone Transformerwood? Selected red beech veneers from highest quality are used Of all known timbers the wood of the red beech (Fagus sylvatica) has the best electrical and mechanical characteristics with respect to the use as insulation material in oil-filled transformers. These trees only grow in Europe. The peeled veneers used for Lignostone Transformerwood are subject to stringent quality specifications and come from sustainable forest management. Large dimensions up to 4,200 x 3,400 mm Large sheets and tangentially layered rings allow the production of large-sized, one-piece components, such as pressure rings and beams, with high mechanical strength and exact specific weight. Utilisation of modern hydraulic presses with very close press tolerances Sheets with tight tolerances minimize the need for further processing. In many cases planing or sanding is not necessary. Moisture content < 5 % The lower moisture content reduces the drying time during the vapourphase and thus saves energy and costs. In addition, it reduces the risk of corrosion of metal parts of the active part of the transformer. You are buying wood, not water! Fast oil absorption Due to its continuous capillaries Lignostone Transformerwood can be dried very quickly and filled with oil air-free. This reduces the energy consumption and makes Lignostone Transformerwood resistant to high-voltage. 100% metal detected During its manufacturing Lignostone Transformerwood is tested with modern metal detectors up to four times on potential dangerous metal inclusions. Each veneer is metal checked. Own high-voltage and materials laboratory Röchling has its own laboratories for performing mechanical and electrical testing (up to 200 kv under oil). Thus our products always meet international standards. World-wide machining centres Röchling has its own machining factories, warehouses with semifinished products and qualified partner companies on the spot worldwide. This allows personal counselling, short routes and quick delivery times. We are ISO 9001:2008 certified Our Quality Management System has been certified since 1994 and thus ensures our continuously high product and service quality and process reliability. R&D in cooperation with the University of Osnabrück Unlike any other supplier in the world, we have sound, scientifically exact evidence regarding the electrical properties of our materials. We work closely with the High Voltage Laboratory of the Hochschule Osnabrück University of applied sciences, where we obtain PD values of Lignostone Transformerwood. 劳士领工程塑料公司生产的高效绝缘材料 Lignostone Transformerwood 有将近一百年的悠久历史, 产品广泛应用于浸油变压器 这种出类拔萃的高品质材料在国际变压器产业中享有极高的声誉 Lignostone Transformerwood 有什么特点? 选用高品质的欧洲山毛榉 ( 水青冈 ) 单板就作为绝缘材料在浸油变压器中的应用而言, 在所有众所周知的木材中, 欧洲山毛榉木 ( Fagus sylvatica ) 具有极高的电气稳定性和机械强度 Lignostone Transformerwood 旋切单板仅选用生长在欧洲的树种, 达到了最严格的质量要求, 来源于可持续的林业经济 最大尺寸达 4,200 x 3,400 mm 大型板材和沿切线方向层压环可实现制备压环和横梁等大尺寸机械强度高和比重精确的单件组件 应用层压公差最小的液压层压工艺公差小的板材降低了在其他加工流程中的投入 在许多情况下可放弃刨平或磨削 水份含量 < 5 % 水份含量比较小, 缩短干燥时间, 从而节省能源和降低成本 此外, 变压器有源部件中的金属件腐蚀危险性下降 您买的是木材, 不是水! 吸油快速 Lignostone Transformerwood 由于其有多孔毛细管, 可非常快速脱水, 加油时无空气混入 这就降低了能量消耗, 使 Lignostone Transformerwood 具有耐高电压特性 100% 检查金属杂质 Lignostone Transformerwood 在生产流程中运用最现代的金属探测仪检查可能混入的危险金属杂质达四次 每块投放的单板均进行检查 公司自己的高压电和材料试验室劳士领公司设有自己的试验室, 进行机械和电气检测 ( 在浸油中小于 200 kv ) 因此, 本公司的产品始终符合国际标准 分布在世界各地的生产基地劳士领公司建有自己的生产基地 半成品库房以及高素质的合作企业, 遍及世界 这就实现了面对面咨询 近距离以及快速交货周期 本公司已获得 ISO 9001:2008 认证本公司的质量管理系统自 1994 年以来获得认证, 保证本公司持之以恒的高品质和服务质量以及流程的可靠性 产品研发与德国奥斯纳布吕克大学的合作作为世界上唯一的供应商, 本公司在我们所提供的材料的电气特性上具备健全的 科学严谨的知识体系 为此, 本公司与德国奥斯纳布吕克大学高压电试验室密切合作, 本公司产品送该试验室测定 Lignostone Transformerwood 的 PD 值 Röchling Engineering Plastics I 3
