Cable accessories construction matters needing attentionAddtime：2016/1/4 

21, cable accessories to do the test to pay attention to what?

experimental test wire and cable accessories should not be too close to the semi conductive layer included so prone to breakdown.  

22, how to check the installation of cable accessories is in place?

  elbow type head should be installed to cover the yellow mark line, can hear "bass" sound during the installation process.

23, cable cleaning using silicone grease agent < grease used precautions note grease used precautions precautions, cleaning must be paid attention to in the cleaning cable and cable accessories, right way is: from the end of the wire to down in turn cleaning, not back and forth cleaning, if back and forth cleaning easy to semi conductive layer of small carbon particles components in the main insulation above, reduce the insulation performance. In the use of silicone grease, all surface and surface contact portion should daub grease, it is the role of insulation sealing and lubrication. Why not  

24, can use Vaseline as grease? < because cable accessories is the main component of ternary ethylene propylene rubber, if in Vaseline and the inside of the components of a chemical reaction, destruction of its organizational structure, reduce the insulation performance.

25, what is the dust cap can not replace the insulation cap?

first dust cap and insulation cap has the essential difference. Dust cap just before leaving the factory to prevent dust, to the scene has no effect, only the insulating cap structure and the site of the cable accessories matching  

26, fault indicator of the installation position is a must in the tail end of the stress cone?

  doesn't have to be installed in the tail end of the stress cone, can be placed in the stress cone, trigeminal gloves to any position of the cable. When the installation is generally installed in the bottom of the stress cone, looks tidy and beautiful.  

27, the cable and the terminals of the copper coordination problem?

  live a lot of the situation due to certain reasons caused by cable and terminal material does not correspond to. This condition should be replaced with terminal. Because if cable copper aluminum terminal or aluminum cables with copper terminals will in two kinds of metal junction of electrochemical reaction and reduce the service life of the equipment.  

28, ground wire is not connected to the prison will be what kind of results?

will use the high voltage electroscope inspection shows that there are electrical connections in the ground and at discharge.

29, in the absence of cable, semi conductive layer too much to deal with? The "

" this situation has occurred, the event also don't worry. To take the following measures: semi conductive layer a layer recovery to achieve and original as consistent as possible, ensure and attachment of the semi conducting layer reliable contact. Don't do anything to deal with the term of nature.

30, why should install the stress cone at the end of the main insulation to do guide angle? < on cable accessories, heat shrinkable tube FAQ

is to effectively control the insulation at the end of the axial stress, the insulating material can withstand the allowable range. Two is easy to install, to avoid scratching the inner surface of the stress cone.

31, stripped cable semi conductive layer is scratched when the main insulation of what measures should be taken to remedy the

depends on the depth of the scratch. If a very serious proposal to do, if only scratch the surface, with 40 objective gauze polished smooth after, and clean.  

32, and cable head of the state of the environment have why to ask, is not up to the requirements should take what measures < in accordance with the provisions of the rules, in high humidity, low temperature strictly is not allowed to work. But the majority did not comply with this requirement for the safe operation of the proposed device take corresponding measures. Construction must do a good job in rainy days to protect the work, to avoid the water on the cable accessories, damp. When the temperature is low, the cable should be paid attention to.  

33, should be at the end of the stress cone seal to solve, < methods of rational effect of which kinds of method 1   insulating waterproof tape wrapped around the outside, and then wrapped a layer of PVC tape.  

2   cable when a preset heat shrinkable cable accessories installed. After the stress cone tail shrinkage.  

34, what should be paid attention to when installing a single through casing connection? < in single pass pipe installation, should not be too hard, otherwise it will the casing connection bolt wring, recommended screw seven and a half times is appropriate. What is the function of T- and  

35 III?  what use it which will be used in it which will be used in it which will use it solve a line, there are multiple outlet. In line to install arresters will also install voltage transformer or a road line and the first two of any group.

36, why some cable head electric transmission test with high voltage electroscope will display electricity? The main reason is there is a potential difference of  

  is a semi conductive layer lap is not good   two is the ground virtual connection.
