Electrical Insulation
Lamina Dielectrics produces many products used for electrical insulation. Our spiral winding, layflat, extrusion and other processes mean that we can offer better technical solutions for electrical insulation applications. Some examples of electrical insulation applications are shown below. If you have a new application needing electrical insulation tubes, sleeves or caps, please contact us to see if we can help you
Motor Winding Connection Insulation
Industrial and domestic electric motors need low cost, high performance insulation for winding connections. This insulation has to withstand high temperatures, high over voltages and yet remain tough enough to withstand high compressive forces during the manufacture of the motor. Some applications are even more demanding, such as hermetically sealed compressors for refrigeration which require the use of materials with proven refrigerant compatibility.
The best solution for this type of application for temperatures up to 150C is to use HSNO caps. Made from UL approved materials, with shrinkable inner layers and tough non shrinkable outer layers, they are easily slipped over connections and hot air is then applied to shrink the inner layers tightly onto the connection.
Making Electric Motors Safer
Domestic and industrial electric motors can overheat and cause fires. To prevent overheating motor manufacturers fit thermal cutouts within the motor windings to stop the motor before it overheats. These thermal cutouts have to withstand the motor overtemperature and yet still ensure good electrical insulation. We supply many of the market leaders with shrink fit insulation tube for high temperature thermal cut-outs.
Flexible Sleeving
Highly flexible sleeving is needed to protect and contain motor lead wires within a refrigerator compressor. If the sleeving is too stiff, noise is transmitted from the motor to the compressor housing. The sleeving is immersed in the refrigerant fluid so it is also important that it is made from a very inert material. Our ETFE layflat tube is used within the refrigeration industry to help our customers achieve the very low noise levels expected from modern refrigerators.
Protection from Electric Shock from Bathroom Heating Rails
Our high temperature multilayer polyimide tubing can also be used to insulate cartridge and other tubular heaters in domestic heating applications.
