一、低电感电缆  
A, low inductance cable
   有强电与弱电之分，这里介绍一种强电用低感电缆。此电缆带有热耗散装置，用于各类接触焊机、电弧焊机与气动焊钳间相连接的新型水冷式低感电缆，具有结构简单合理、冷却水流通量大、耐磨阻漏热电偶不会形成堵塞阻断和限流现象、散热效果好、使用寿命长等特点。  
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..
   这种新型低感电缆也包括电缆和电缆端头上固装着的接头，且电缆也是由正极缆芯和负极缆芯同装于外胶管中构成。由于这类低感电缆一般都是用于电压为25-50V、电流在7000-12000A之间的场合，冷却水在电缆中的短路导电现象基本上可忽略不计。
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.
   所以在此低感电缆中没有使用隔离正极缆芯和负极缆芯的橡胶软管，只是特别设置了一条横断面呈轮辐状（俗称“梅花芯"状）的芯架，其“轮心"和相邻“辐条"间所围成的空间在顺轴线方向上即形成纵向沟槽，芯架上的纵向沟槽与电缆所配置的正极缆芯的总根数相同，其电缆部分就是以正极缆芯和负极缆芯分别搁于芯架的纵向沟槽内装置在外胶管中构成。
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.
   硅橡胶扁电缆正极缆芯和负极缆芯的两端头部分别同极集合成束夹固于缆芯夹中，然后固装在接头上，电缆的外胶管的端头部套装在接头的尾端部，并用套装在外胶管外的收紧箍紧密封。  
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、低噪音电缆
Two, low noise cable
   在弯曲、振动、冲击、温度变化等外界因素作用下，电缆本身产生的脉冲信号小于5mV的电缆称为低噪音电缆，也称防震仪表电缆。用于工业、医学、国防等多个领域微小信号的测量。有聚乙烯绝缘低噪音电缆、F46绝缘低噪音电缆、耐辐照低噪音电缆、低电容低噪音电缆、水听器电缆、水密低噪音电缆等多种型号规格的电缆。  
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.
认为电缆中产生噪音的原因有：
That noise cause cable in the:
   1、介质本身内部分子摩擦；
1, the medium itself within the molecular friction;
   2、电缆电容的改变；
2, the cable capacitance change;
   3、电缆介质的压电效应；
Piezoelectric effect 3, cable dielectric;
   4、电缆中导体和介质摩擦产生电荷，即当导体和绝缘之间接触破坏时产生电荷的分离。  
The charge generating conductor and dielectric friction 4, cable, separation is when the conductor and insulation between the contact damage produce charge.
   在聚乙烯绝缘表面挤上一层薄薄半导电（厚度0.20-0.30mm）的低噪音电缆得到了迅速的发展，其噪音值在2-3mV，对于工作在400度的低噪音电缆，可采用耐高温半导电纤维绕包的办法来解决，其噪音可达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.
   我国电线电缆行业是仅次于国内汽车行业的第二大行业。在世界范围内，我国电线电缆总产值已超过日本仅次于美国，是*二大电线电缆生产国。随着市场需求的不断增长，近年来，电线电缆行业整体发展速度很快，新增企业数量不断上升，行业整体技术水平得到大幅提高。
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.
   在未来一个时期，电力、轨道交通、通信、船舶等产业依然保持较大的投资规模，《2007年全国电力市场分析预测(年度)报告》。报告预计，2007年全国GDP增速将低于2006年水平，增长9.5％～10.3%，全社会用电量增长11％～12.5%，达到31300亿～31800亿千瓦时。未来五年，中国在电力发展结构上将大力开发水电，着重加快核电和天然气建设速度，根据需要，发电方面的投资需要一万亿元，电网投资规模业将达到七千五百亿元。
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，发改委发布的《可再生能源发展“十一五"规划》中，将2010年风电装机容量的目标定为1000万千瓦，是届时核电计划的装机容量的1/2。全国各地也大力发展电力设施，如北京6区县增建10座变电站、山东将建设5个风电场、湖南内陆核电建设提速等，这必将给电线电缆行业提供难得的机遇。目前，我国电线电缆行业正处于发展的快速增长期。
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.
