The introduction of fixed head

Cable sealing sleeve is a suitable connection cable power supply, also can protect the cable, so it won't escape. Cable sealing device is placed in different categories,depending on whether the glands for general processing industry or in need of protection, prevent the risk is too high or the explosion temperature. Into the armored cable glands or no armoring layer and a different type of gland will be required for each variety. The gland itself, can be made of metal, such as copper or aluminum, or plastic, the material is useful in different environments.

When the electrical work is completed, it may be no cable sealing, to ensure theelectrical equipment wire, but there are several reasons, this is a bad idea. Glandsprovide sealing power, so as to ensure that the RCA audio cable will not slip during operation.Security is also provided, because the cable gland to ensure that electricity can not attached to anyone nearby, causing bodily harm. Glands usually provide other safety features, such as the earth wire or insulated cable.

To have two categories: Industrial and hazardous for RCA video cable sealing. Industrial cablesealing joint is a general use of the gland, in order to meet the requirements ofgeneral risk, so it is useful or dangerous explosion in high-temperature environments.If the environment is harmful substances, the use of dangerous gland, because these glands to meet additional requirements necessary. They are fortified with extra, so that they can resist common glands cannot withstand the temperature and external forces.

Two types of cables can be sealed sleeve is classified as armored or unarmoredcable into, which will play glands work will rebound. Armored cat6 ethernet cable will need a gland,can clip into the wire, and the ability to terminate the energy from the armor part. Nonarmoured line does not require termination, but the glands need highly protected andpreserved, in order to maintain the safety of wire.

Most cable gland cell is made from brass, which is considered, as a general materialis resistant to corrosion and electrical conductivity. In the aluminum and the presence of moisture at the same time, the corrosion of brass can start. Brass is often associated with other metal plating, to make the gland is stronger, better corrosion.Plastic is often used as an alternative to metal glands.

Cable industry prospects

With the wire and cable industry competition intensified, large wire and cableenterprises merging and capital operation is becoming more frequent, the domestic wire and cable production enterprises outstanding more and more research and attention to the industry market, especially the thorough research to the enterprise development environment and customer demand trend change. Because of this, a large number of outstanding domestic wire and cable brand rapidly, graduallybecome a leader in the wire and cable industry!

Wire and cable industry report mainly analyzes the operation situation and Prospect Forecast of electric wire and cable industry; power cable products market demand forecasting and purchasing; communication cable products market demand forecasting and purchasing; electrical equipment market condition of the cable; bare wires and wire winding market; competition pattern and competitor wire cableenterprises; development status and the planning of industrial base of wire and cable;construction trend of wire and cable industry base project; the wire and cable industryanalysis and solve problems existing measures and suggestions. At the same time,accompanied by the whole industry for nearly 5 years the comprehensive detailedhand continuous market data, market trends and the development trend of lets you fully, accurately grasp the wire and cable industry. Although the Chinese wire and cable industry has experienced more than 20 years, has made considerable development, but still not out of the big and not strong cycle, are still a big gap compared with world class companies. The existence of industry concentration is low,a large number of enterprises and small scale, the scale economy is far from enough,lack of the capability of independent innovation and product structural contradictionand so on many questions. Despite these problems, but the Chinese wire and cableindustry is facing new opportunities that the rapid take-off, enhance their corecompetitiveness opportunities in development. With the changing of world economic pattern, Chinese mini DVI cable industry is also bound to face restructuring and reshuffle.Especially in Chinese economic development in recent years is facing the problem ofbottleneck of energy, electric power shortage, the state has continued to increasepower investment, the industry entered a period of leap forward development. Toimplement the central decision-making deployment of the construction of infrastructure, stimulating domestic demand, the China State Grid Corp plans to increase investment, accelerate the pace of construction of power grids, it is expected that in the next 2 to 3 years the scale of investment will exceed 1 yuan, of which rural city and the main power grid construction and transformation of investment 790000000000 yuan. The construction scale of 110 (66) kV and above transmissionline 260000 km, 13.5 million KVA substation capacity.

Industry equipment belongs to a power cate5e network cable manufacturing industry for power transmission, the relatively low technological content, low barriers to entry, the user is mainly the China State Grid Corp, this market lead to the loss of pricing power for many equipment suppliers, the entire industry after the rapid expansion and raw materials prices after the facing problems, the industry increasingly fierce competition, profits are a declining trend; the two power transmission equipment industry is a cyclical fluctuations relatively small industry, it relates to the high-tech field, technical barriers to high, by a few large companies monopoly. In view of the development prospects of China's power industry, as its sub industries in the promotion of the environment is still expanding space better wire and cable manufacturing industry.

Cable use scope

Power system

Wire and cable products used in the power system mainly has the overhead bare wire,bus (bus), the power cables (plastic cable, oil paper power cable (basically replace the plastic power cables), rubber set of cable, aerial insulated cables), branch cable(instead of part of the bus), electric magnetic line with electrical equipment and power equipment wire and cable etc..

Information transmission system

For information transmission system wire and cable are mainly telephone cable, TV cable, electronic fiber optics cables , radio frequency cable, fiber optic cable, data cable,electromagnetic wire, electric power communication or other composite cable.

Mechanical instrumentation system in addition to this part of the overhead bare wiresoutside almost all other products are applied, but the main power optical fiber cable ,electromagnetic wire, data cable, instrumentation cables

Optional elements of cable

Wire and cable as the main carrier of power transmission, are widely used inelectrical equipment, lighting, household appliances and other lines, its quality directlyaffects the quality of the project and the life and property safety of consumers. There are a lot of wire varieties on the market, want to use the appropriate wire according to the power load your.

On the market sell wire some cheap and some more expensive, some people oftenbut to relatively cheap, cheap, wires, often have many did not reach the performancethat he shows, there may bring many security hidden trouble to yourself. Productiontechnology content of wire is not too high, the raw material is not much difference, if cheap too much, or cut corners, or the number of not giving enough. How to identify it. I give you several micro usb cable for easier identification:

1, to look at the packaging, GB wires tend to do relatively well, neat, hand up have asense of quality.

2, to open the package to see the inside of the wire, the wire GB 1.5 - -6 square wirerequirement is thick skinned (insulation thickness) is 0.7mm, too thick is non-standard, corresponding to his inner core is sure enough, line skin you can force pull,not easy to tear is general is the national standard of

3, with the fire, extinguished within 5S after leaving, have certain flame retardant function for GB line.

4, look at the inner core, the inner core material (copper) brightness higher copper is better, and photometric uniform, shiny, no sense of hierarchy. The national standard requirements within the core must use oxygen free copper. Non standard such asblack rod copper, there may be hidden dangers of accidents.

5, the thickness of inner core countries have certain requirements, but not very strict.But not a lot of mistakes, only a very small a little bit error generally with the eyes of the.

6, length, no compulsory must play fiber optic cable , but there are many manufacturers alsoplayed meters, not necessarily GB dozen meters, but the General GB generally notdozen meters. Non standard dozen meters that is only a kind of means.

7, the provisions of the state on the wires must play a certain identity, the maximumnot more than 500mm have identified the same next play out, above the generalproduct trademark, factory name, the implementation of standards
