Application of Thermal Shrinkage Casing in Controller

- Apr 26, 2019-

A company concentrates on the design and manufacture of controllers, and always leads the world in the fields of Aeronautical industry, transportation, power generation, industrial production of engines and turbine controllers. It produces mechanical and hydraulic governors, provides electro-jet and electronic speed regulation technology and products, and provides after-sales services and spare parts procurement in the fields of industry, ship and land power generation. The company uses many kinds of heat shrinkable tubes: single-wall tube, double-wall tube, mother row heat shrinkable tube and special insulating sleeve, etc. Let's analyze the application of heat shrinkable tube in the controller.

We know that everything involved in electricity is inseparable from insulation protection. Controllers change the connection of main circuit or control circuit in a predetermined order and change the resistance value in the circuit to control the startup, speed regulation, braking and reverse of the motor. Of course, insulation protection is also inseparable. When it comes to insulation protection, the best way is to use heat shrinkable tubes.

Heat shrinkable pipes are made of radiation crosslinked polyolefin materials with excellent physical, chemical and electrical properties. The main functions of heat shrinkable pipes are electrical insulation of connectors, rust and corrosion prevention of solder joints, mechanical protection and wire harness protection, etc. They are widely used in controllers.

It should be noted that there are many kinds of controllers, such as the controllers in desktop computer mainframe. The insulation protection of this kind of controllers can be achieved by using ordinary heat-shrinkable tubes, which can withstand 600 V sealing and corrosion protection. Large controllers such as bus controllers need to use heat-shrinkable tubes of bus bars for insulation protection, because buses are classified according to withstand voltage, while 10KV bus bars need withstand voltage. The insulation of heat-shrinkable pipes with equivalent value greater than 10KV can reduce the distance between them and improve the construction safety.
