A company focused on the design and manufacture of controllers, and always in the aviation industry, transportation, power generation, industrial production of engines and turbine controllers in the field of the world's leading level, the production of mechanical hydraulic governor, to provide electric spray and electronic speed regulation technology and products, to provide industrial, marine, land power generation and other fields of after-sales service and spare parts procurement The company uses more types of heat shrinkable tubes: single-walled tubes, double-walled tubes, parent-drain heat shrinkable tubes and special insulating sleeves, and so on, let's analyze the application of heat shrinkable tubes in the controller.

We know that everything involved in electricity is inseparable from insulation protection, the controller is in accordance with the predetermined order of the main circuit or control circuit wiring and change the resistance value in the circuit to control the motor start, speed regulation, braking and reverse of the main device, of course, can not be separated from insulation protection, mentioned insulation protection, the best way is to use heat shrinkable tube

The heat shrinkable tube is made of radiant crosslinked polyolefin material, the physical and chemical properties are excellent, the main function is the electrical insulation of the connecting parts, the welding point anti-rust and anti-corrosion, mechanical protection and wire harness protection, etc., which are widely used in the controller.

It should be noted that the controller is divided into many kinds, common such as the desktop computer mainframe controller, this controller insulation protection selection of ordinary heat shrinkable tube can be, pressure resistance 600V seal anticorrosion; Large controllers such as Busbar controllers need to use the parent drain heat shrinkable tube to insulation protection, because the busbar according to the pressure resistance has a certain grade division, The 10KV parent row needs the heat shrinkable tube insulation which is more pressure-resistant equivalent than 10KV, reduces the meet distance and improves the construction safety.

热缩套管在控制器中的案例

某公司专注于控制器的设计与制造，并始终在航空工业、交通运输、发电、工业生产的发动机及透平控制器领域处于世界领先水平，生产机械液压调速器, 提供电喷和电子调速技术及产品，提供工业、船舶、陆地发电等领域的售后服务和备品采购。该公司使用的热缩管品种较多：单壁管，双壁管，母排热缩管以及特种绝缘套管等等，下面我们来分析一下控制器中热缩管的应用。

我们知道凡事牵扯到电的都离不开绝缘防护，控制器则是按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置，当然也离不开绝缘防护，提到绝缘防护，那最好的方法就是使用热缩管。

热缩管由辐射交联聚烯烃材料制成，理化电气性能优异，主要功能是连接件的电绝缘、焊点防锈防腐、机械防护和线束防护等，在控制器中的使用非常广泛。

需要注意的是，控制器分很多种，常见的的如台式电脑主机中的控制器，这种控制器的绝缘防护选用普通的热缩管就可以了，耐压600V密封防腐；大型控制器如母线控制器则需要用到母排热缩管来绝缘防护，因为母线根据耐压有一定的等级划分，10KV母排则需要耐压等价大于10KV的热缩管绝缘，缩减相见距，提高施工安全。
