解析滑觸線的用途和需要注意的安全事故-蘇博滑觸線

一、低電感電纜  
A, low inductance cable
   有強電與弱電之分，這里介紹一種強電用低感電纜。此電纜帶有熱耗散裝置，用于各類接觸焊機、電弧焊機與氣動焊鉗間相連接的新型水冷式低感電纜，具有結構簡單合理、冷卻水流通量大、耐磨阻漏熱電偶不會形成堵塞阻斷和限流現象、散熱效果好、使用壽命長等特點。  
There is a strong electricity and weak electricity division, here introduces a kind of strong low cable. This cable with heat dissipation device, used for various contact welding, arc welding machine and pneumatic novel water-cooled electrode holder is connected with low cable, has the advantages of simple and reasonable structure, cooling water flux, high wear resistance leakage thermocouple not be clogged up blocking and limit the characteristics of flow phenomenon, good heat dissipation effect, and long service life etc..
   這種新型低感電纜也包括電纜和電纜端頭上固裝著的接頭，且電纜也是由正極纜芯和負極纜芯同裝于外膠管中構成。由于這類低感電纜一般都是用于電壓為25-50V、電流在7000-12000A之間的場合，冷卻水在電纜中的短路導電現象基本上可忽略不計。
The new type low cable also includes a connector cables and cable terminal head is fixed, and the cable is composed of positive and negative with the cable core cable core is arranged in the outer tube. Because this kind of low cable is generally used for voltage, current situations of 25-50V between 7000-12000A, short circuit conducting phenomenon in the cable in the cooling water basically negligible.
   所以在此低感電纜中沒有使用隔離正極纜芯和負極纜芯的橡膠軟管，只是特別設置了一條橫斷面呈輪輻狀（俗稱“梅花芯"狀）的芯架，其“輪心"和相鄰“輻條"間所圍成的空間在順軸線方向上即形成縱向溝槽，芯架上的縱向溝槽與電纜所配置的正極纜芯的總根數相同，其電纜部分就是以正極纜芯和負極纜芯分別擱于芯架的縱向溝槽內裝置在外膠管中構成。
So in this sense of isolation and low rubber hose anode cable core and the negative cable core without the use of cable, is especially provided a cross section which is shaped (commonly known as the "plum blossom shape the core frame core"), the "wheel" spokes "heart" and the adjacent room enclosed space in the CIS axis direction that the formation of longitudinal grooves, total root number positive cable core longitudinal grooves and the cable core frame configured the same longitudinal grooves, the cable is the cable core part to positive and negative cable cores are respectively put on the core frame inner device formed in the outer tube.
   硅橡膠扁電纜正極纜芯和負極纜芯的兩端頭部分別同極集合成束夾固于纜芯夾中，然后固裝在接頭上，電纜的外膠管的端頭部套裝在接頭的尾端部，并用套裝在外膠管外的收緊箍緊密封。  
Two heads of silicone rubber flat cable positive cable core and the negative cable core homopolar assemble bundle respectively clamped on the cable core in a folder, and then is fixedly arranged on the joint, the outer rubber tube cable head is sheathed on the joint of the tail end, and is sheathed in the outer hose outside the tightening hoop seal.
二、低噪音電纜
Two, low noise cable
   在彎曲、振動、沖擊、溫度變化等外界因素作用下，電纜本身產生的脈沖信號小于5mV的電纜稱為低噪音電纜，也稱防震儀表電纜。用于工業、醫學、國防等多個領域微小信號的測量。有聚乙烯絕緣低噪音電纜、F46絕緣低噪音電纜、耐輻照低噪音電纜、低電容低噪音電纜、水聽器電纜、水密低噪音電纜等多種型號規格的電纜。  
In the role of external factors of bending, vibration, shock, temperature change, the cable itself produces pulse signal is smaller than the 5mV cable is called the low noise cable, also known as the earthquake instrument cable. For the measurement of a plurality of areas of industrial, medical, defense and other small signal. Cable with polyethylene insulation low noise cable, F46 insulated cable, low noise radiation resistant, low noise cable, low noise, low capacitance cable hydrophone cable, water tight low noise cable and so on the many kinds of types and specifications.
認為電纜中產生噪音的原因有：
That noise cause cable in the:
   1、介質本身內部分子摩擦；
1, the medium itself within the molecular friction;
   2、電纜電容的改變；
2, the cable capacitance change;
   3、電纜介質的壓電效應；
Piezoelectric effect 3, cable dielectric;
   4、電纜中導體和介質摩擦產生電荷，即當導體和絕緣之間接觸破壞時產生電荷的分離。  
The charge generating conductor and dielectric friction 4, cable, separation is when the conductor and insulation between the contact damage produce charge.
   在聚乙烯絕緣表面擠上一層薄薄半導電（厚度0.20-0.30mm）的低噪音電纜得到了迅速的發展，其噪音值在2-3mV，對于工作在400度的低噪音電纜，可采用耐高溫半導電纖維繞包的辦法來解決，其噪音可達5mV。
In the polyethylene insulation surface squeeze on a thin layer of semi conductive (thickness 0.20-0.30mm) low noise cable obtained the rapid development, the noise value in 2-3mV, for the work in the 400 degree low noise cable, can use high temperature resistant semi conductive fiber winding package solution, the noise of up to 5mV.
   我國電線電纜行業是僅次于國內汽車行業的第二大行業。在世界范圍內，我國電線電纜總產值已超過日本僅次于美國，是*二大電線電纜生產國。隨著市場需求的不斷增長，近年來，電線電纜行業整體發展速度很快，新增企業數量不斷上升，行業整體技術水平得到大幅提高。
China's wire and cable industry is the second largest industry after the domestic auto industry. In the world scope, wire and cable in China total output value has exceeded Japan after the United States, is the world's second largest producer of wire and cable. With the increasing demand of the market, in recent years, electric wire and cable industry as a whole the development speed is very fast, the growing number of new enterprises, the industry overall technological level has been greatly improved.
   在未來一個時期，電力、軌道交通、通信、船舶等產業依然保持較大的投資規模，《2007年全國電力市場分析預測(年度)報告》。報告預計，2007年全國GDP增速將低于2006年水平，增長9.5％～10.3%，全社會用電量增長11％～12.5%，達到31300億～31800億千瓦時。未來五年，中國在電力發展結構上將大力開發水電，著重加快核電和天然氣建設速度，根據需要，發電方面的投資需要一萬億元，電網投資規模業將達到七千五百億元。
In the future a period, electricity, rail transportation, communication, ship industry still maintained a large scale of investment, "analysis and prediction of the national electricity market in 2007 (year) report". Report is expected, in 2007 the national GDP growth will be lower than the 2006 level, growth of 9.5% ~ 10.3%, the whole society electricity consumption growth of 11% to 12.5%, up to 3130000000000 ~ 3180000000000 kwh. The next five years, China vigorously develop hydropower in the structure, electric power development, mainly to accelerate the building of nuclear power and natural gas speed, according to the needs, power generation investment needs one trillion yuan, the scale of power grid investment industry will reach seven hundred and fifty billion yuan.
   今年3月，發改委發布的《可再生能源發展“十一五"規劃》中，將2010年風電裝機容量的目標定為1000萬千瓦，是屆時核電計劃的裝機容量的1/2。全國各地也大力發展電力設施，如北京6區縣增建10座變電站、山東將建設5個風電場、湖南內陸核電建設提速等，這必將給電線電纜行業提供難得的機遇。目前，我國電線電纜行業正處于發展的快速增長期。
In March this year, the national development and Reform Commission issued the "renewable energy development" eleven five "planning", will be 2010 wind power installed capacity target of 10000000 kilowatts, nuclear power plan is then installed capacity of 1/2. The country also vigorously develop the power facilities, such as the 6 districts and counties of Beijing built 10 substations, Shandong will build 5 wind farms, Hunan inland nuclear power plant construction speed and so on, which will provide a rare opportunity for the wire and cable industry. At present, China's wire and cable industry is in rapid growth development period.
