How to clean Cable Accessories

Insulation treatment should be carried out when cable accessories are installed on site, In addition to the impact of climate conditions on installation quality, dust and debris in the environment will have adverse effects, especially when installing cable accessories.

△Clean up the dust after shrinkage
The on-site installation of heat shrinkable cable accessories is currently limited to the use of liquefied gas spray gun, gasoline blowtorch and other heat sources, no matter what fuel is used, such as insufficient flame combustion, containing a lot of carbon dust. In the process of uniform heating back and forth, a layer of dust particles will be coated on the surface of the heat-shrinkable material. If not removed, it will be extremely harmful. It will cause poor contact between insulating layers, insulation decline, leakage current increase, poor bonding of rain shed and other problems. Therefore, it is a very important operation step to clean the surface with solvent after shrinking each tube fitting in the process. 

△Remove grease to ensure sealing effect
The sealing structure of the heat-shrinkable cable accessories is sealed by sealing mastic, which tightly binds the tube to the tube and the tube to the metal to block the oil leakage and moisture immersion. The key to bonding is to clean the bonding interface well, and the surface with oil can not have a good bonding effect, so in the sealing part to shrink the tube before careful cleaning with solvent, in order to ensure the sealing effect.

△About the choice of solvent
The effect of clean plastic surface and purify smeary has direct relation with the solvent that uses, according to relevant data introduction is good with the solvent effect such as trichloroethylene, acetone. If you scrub the surface of plastic with ethanol (solvent), the surface resistance of dissolved thorn is zero after play with remote meter measurement, so it is not suitable for use, and ordinary gasoline contains a variety of metal oxides, not to use.

As for the choice of solvent, it is very important to clean the surface of XLPE insulation, so we should pay attention to it. We will provide free built-in cleaning tissue in the Heat Shrinkable & Cold Shrinkable Termination kit and Straight Through Joint kit, which are also suitable for solvent cleaning effect.
