聚氨酯双绞双护套屏蔽拖链电缆

名称：聚氨酯双绞双护套屏蔽拖链电缆

Name: Polyurethane twisted pair and double sheath shielded drag chain cable

应用领域

该电缆采用线芯对绞整体屏蔽结构，可用于易受到外部高频电场影响造成干扰的传输场合。适用于较度恶劣环境下的户外以及室内场合，有着良好的抗撕裂和耐磨性，及良好耐矿物油、耐制冷剂、耐水解、抗霉菌等特性。高密度高电导率材料组成的网状屏蔽层，和采用挤压式内护套结构可更为有效的固定线芯的位置，可确保电缆在往复弯曲的过程中线芯有序的移动提高弯曲寿命，同时具有较强的抗干扰能力。可用于钢铁厂、矿山机械、北方寒冷的户外、湿润和潮湿的室内及露天环境中以及能源拖链、工业机器人、生产线、自动化控制系统中，和其他需要高速往复移动的应用场合。

Application

The cable adopts the core-shield twisted overall shielding structure, which can be used for transmission occasions that are easily affected by external high-frequency electric fields. It is suitable for outdoor and indoor occasions in extremely harsh environments. It has good resistance to tearing and abrasion, and good resistance to mineral oil, refrigerant, hydrolysis, and mold. The mesh-shaped shielding layer composed of high-density and high-conductivity materials, and the use of an extruded inner sheath structure can more effectively fix the position of the core, which can ensure the orderly movement of the core during the reciprocating bending of the cable and increase the bending life. At the same time, it has strong anti-interference ability. It can be used in steel plants, mining machinery, cold outdoor, wet and humid indoor and outdoor environments in the north, energy chains, industrial robots, production lines, automated control systems, and other applications requiring high-speed reciprocating movement.
