Description
所属技术领域Technical field
本实用新型涉及一种乙丙绝缘风能专用电缆，属电线电缆技术领域。The utility model relates to an ethylene-propylene insulated special cable for wind energy, which belongs to the technical field of electric wires and cables.
背景技术 Background technique
目前，风能发电用耐扭转电缆多采用普通橡套电缆，该电缆使用寿命短，不能满足风能电缆安全运行20年的使用要求，经常因电缆损坏而造成设备停止转动，严重影响了用户的使用效果，给用户造成很大的损失。At present, the torsion-resistant cables for wind power generation mostly use ordinary rubber-sheathed cables, which have a short service life and cannot meet the requirements for safe operation of wind power cables for 20 years. The equipment often stops rotating due to cable damage, which seriously affects the user's use effect. , causing great losses to users.
发明内容 Contents of the invention
本实用新型的目的是提供一种具有良好的电气性能、柔软性好、抗拉强度高及耐、抗扭转性能高和使用寿命长的乙丙绝缘风能专用电缆。The purpose of this utility model is to provide a special cable for wind energy with good electrical performance, good flexibility, high tensile strength, high resistance to torsion, high resistance to torsion and long service life.
本实用新型的技术方案是：一种乙丙绝缘风能专用电缆，它由铜导体、隔离层、绝缘层和外护套组成。在单根或多根特软且伸长率均匀的铜导体上均匀绕包一层隔离层。在隔离层上挤包一层由特软乙丙绝缘混合料构成的绝缘层。在绝缘层上挤包一层由高强度氯磺化聚乙烯混合料构成的外护套。The technical solution of the utility model is: an ethylene-propylene insulated wind energy special cable, which is composed of a copper conductor, an isolation layer, an insulating layer and an outer sheath. A layer of isolation layer is evenly wrapped on a single or multiple copper conductors that are extremely soft and have uniform elongation. An insulating layer made of extra soft ethylene-propylene insulating compound is extruded on the insulating layer. An outer sheath made of high-strength chlorosulfonated polyethylene compound is extruded on the insulating layer.
本实用新型适用于额定电压0.6/1kV等级及0.6kV以下等级的乙丙绝缘风能专用电缆。The utility model is suitable for the ethylene-propylene insulated wind energy special cable with a rated voltage of 0.6/1kV and below 0.6kV.
本实用新型的有益效果是：由于采用了特软且伸长率均匀的铜导体，大大提高了电缆的抗扭转性能。由于在绝缘层和导体之间设置了隔离层，增加了导体与绝缘层之间的相对滑移，从而提高了电缆的抗扭转能力。由于采用了绝缘性能较好的特软乙丙绝缘混合料作为绝缘层，使本电缆的最高长期工作温度提高到90℃，从而提高了电缆的电气性能。由于采用氯磺化聚乙烯混合物作为外护套，使护套具有较高的机械性能，从而大大提高了电缆的耐扭转性能，该护套还具有耐盐雾、抗老化、耐低温等良好的电气性能。综上所述，本实用新型提供了一种具有良好的电气性能、柔软性好、抗拉强度高及耐、抗扭转性能高和使用寿命长的乙丙绝缘风能专用电缆。The beneficial effect of the utility model is that the torsion resistance performance of the cable is greatly improved due to the adoption of the extra soft copper conductor with uniform elongation. Since the isolation layer is set between the insulating layer and the conductor, the relative slip between the conductor and the insulating layer is increased, thereby improving the torsion resistance of the cable. Due to the use of extra-soft ethylene-propylene insulating compound with better insulation performance as the insulation layer, the maximum long-term working temperature of the cable is raised to 90°C, thereby improving the electrical performance of the cable. Due to the use of chlorosulfonated polyethylene mixture as the outer sheath, the sheath has high mechanical properties, which greatly improves the torsion resistance of the cable. The sheath also has good salt spray resistance, anti-aging, low temperature resistance, etc. Electrical performance. In summary, the utility model provides an ethylene-propylene insulated wind energy special cable with good electrical properties, good flexibility, high tensile strength, high resistance to torsion, high resistance to torsion, and long service life.
