As is known to all, electricity insulation protection projects in power engineering is crucial, construction of the project not only requires the installation of insulation protection knowledge, but also have to have some solid exercise experience
The cracking of large section armoured PE cable sheath is a difficult problem that cable manufacturers must face. In order to improve the cracking resistance of PE sheath of cable, it should be controlled from many aspects, such as sheath material itself, cable structure, production technology and laying environment, so as to prolong the service life of cable and ensure the quality of cable.
If there is a mistake in the selection of heat shrinkable tube in the last link, then the heat shrinkable tube can not achieve the protection effect of the cable well, and it is likely to have a bad effect on the whole circuit.
At present, the commonly used heat shrinkable tube materials are mainly divided into polyethylene, polyvinylidene fluoride, fluorine rubber, polytetrafluoroethylene these four materials, for manufacturers, polyethylene is the most cost-effective production of heat shrinkable tube raw materials, but also one of the most widely sold raw materials.
Heat Shrinkable Double-walled Tube and LV Heat Shrinkable Thin Wall Tube belong to heat shrinkable pipe, both have the function of heating and shrinking, the difference between the two is only the morphological structure and the main application scenarios.
As a kind of common insulating tube, Heat Shrinkable Insulation Tube has become an important part of electrical and electrician all over the world. How to select high quality Heat Shrinkable Insulation Tube has become the theme of today, the following five factors affecting the quality of Heat Shrinkable Insulation Tube are provided
