The Production and Sales of Various Terminals

What are the factors that make hV Copper Terminals fail?  
1. The site conditions are relatively poor. The environment and technical requirements of copper pipe Terminals and joints are very high when they are manufactured in the factory, while the temperature, humidity and dust at the construction site are not well controlled.  
2. The installation is not strictly in accordance with the technical construction or technical rules without considering the questions that may be presented.  Dc withstand voltage test is selected for completion inspection to constitute anti-electric field in the joint, resulting in insulation damage.  
3, due to poor sealing treatment.  The center joint must choose the metal copper shell plus PE or PVC insulation anticorrosive layer of the sealing structure, in the field construction to ensure the tightness of the lead seal, so effectively ensure the sealing waterproof function of the joint.  
4, copper pipe terminal construction process in the insulation surface will inevitably leave subtle skid marks, semi-conductive particles and sand on the emery cloth may also be embedded in the insulation, other joint construction process because of insulation exposure to the air, insulation will also inhale water, these leave danger for long time safe operation.  
5, the brass terminals material itself and the brass terminals manufacturing, installation, inevitably exist in the process of terminal manufacturing defects, the operation of the electric heating, chemical, environmental factors influence, the insulation of the brass terminals will attack different degree of aging, the aging will eventually led to the outbreak of the brass terminals with.
