gui chao cable news: active service customers, so that users really satisfied-非凡电子娱乐

customer service in the service process of cable products, we often encounter such users, they buy the cable products, often because of the construction or the use of improper use of cable caused by power failure occurred after the initial. as a result of some users do not have the ability to detect the fault of the field cable, cable manufacturers will be required to assist in the field of fault location and cause analysis services. cable fault location of the service staff, have such experience, to ensure the quality of service of the cable field troubleshooting, as the sales staff need to do the following three aspects of the preparatory work.

1, active and effective communication with the user, fully understand the actual situation of the scene, before the start of all kinds of inspection equipment. need to carry digital camera when necessary. notebook computers and u disk.

because the current professional cable fault detection equipment purchased from the market, divided into two parts of high voltage and low voltage, for different types of cable fault site, the equipment may be different. if you do not fully understand the situation on the scene before the start, carrying equipment is not enough or insufficient, it will greatly delay the time to repair the cable failure, causing greater economic losses to the user. this situation for close service may have little effect, but for the long distance remote fault localization services, the time delay could be considerable. greatly affected the actual service effect of the cable.

2 be fully aware of and prepare for the harsh environment of cable fault.

cable use is changeable, may be used in a desolate desert oil base,. may also be used in the coal mine, there may be used in the big gobi on the newly established a variety of chemical plants and cement plants, etc.. and most of all at the outdoor cable, cable, cable tray, most of the buried ditch tunnel laying etc.. the desert and gobi, the temperature difference between day and night on the scene, outdoor buried cable fault location precision fixed-point process may be in the daytime, when the surface temperature may reach 40 degrees celsius above zero, there may be at night, when the temperature dropped to minus 15 degrees celsius to. when the cable fault point is measured smoothly, the detection process will be completed within 1-2 hours, but when the special fault and the lack of practical experience in the field of positioning of the test personnel, often take a few hours or even a few days time. in the event of a continuous fault location in such a climate environment, the service staff must be fully aware of the weather and environmental conditions in advance. all kinds of cold prepared on-site continuous work clothes and prepare heatstroke. in the field of service to prevent the process of causing physical damage, affecting the efficiency of on-site service.

use the cable tray, often in more than ten meters above the height. if the fault point is located in the high altitude on the cable tray. often need to wear safety belt on the bridge service personnel to assist the user to aerial patrol line, this service often has certain risk. therefore, to do security work on the bridge before wearing the safety belt, to prevent high-altitude accidental injury. the above examples are only some of the scene we learned, may be the actual situation of the scene than we learned even more complex and changeable. general cable fault location and processing time is very tight. at the same time, the service personnel after receiving the notice usually rushed out. this requires us to arrange the time and travel time in the actual service process, in time for the user to exclude line fault. win customer satisfaction.

the occurrence of the cable fault in the field is often paroxysmal, may occur at night, may also occur during the holidays. and the arrival time of the service personnel is also random, the location of the site and repair service process may be carried out during the day or at night. therefore, the field service personnel must have the spirit of hard work, good physical quality, rich experience in the field of fault location. at the same time, high-precision cable fault detection equipment has become a necessary field service work. the quality of the location of the cable fault location services not only for users to gain valuable repair time, reduce the economic losses of the user. and for cable manufacturers to win the user and market.

3 have strong experience in cable fault detection and rich cable fault analysis

there are many kinds of cable line fault in the actual situation, the actual situation of the cable fault encountered by the service personnel will be different. some of the fault occurred in the cable terminal joints; breakdown occurs only after a fault point of some cable insulation, and some cable insulation breakdown may occur after two or more points of failure; some cable fault occurs after the whole burning scrap cannot be used.

for the different types of cable faults, we must first identify the fault nature of the cable, the appropriate fault detection method. to find the cable fault location. cable insulation fault type according to the characteristic impedance and the on-off circuit conductor can be divided into high resistance and low resistance and open circuit fault detection method for selection of different fault characteristics are different, can be divided into bridge method, low voltage impulse method, impulse method, two pulse, three pulse method etc.. the above method can only be used to measure the fault location of cable and determine the approximate position of cable fault point. in order to realize the precision measurement of the fault point, still need to use acoustic emission and auxiliary audio method and step voltage method. although there are a large number of various types in the market
