Cable industry prospects

With the wire and mini usb cable industry competition intensified, large wire and cable enterprises 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, gradually become 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 mini HDMI 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 cable enterprises; 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 industry analysis and solve problems existing measures and suggestions. At the same time, accompanied by the whole industry for nearly 5 years the comprehensive detailed hand 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 contradiction and so on many questions. Despite these problems, but the Chinese wire and cable industry is facing new opportunities that the rapid take-off, enhance their core competitiveness opportunities in development. With the changing of world economic pattern, Chinese cable industry is also bound to face restructuring and reshuffle. Especially in Chinese economic development in recent years is facing the problem of bottleneck of energy, electric power shortage, the state has continued to increase power investment, the industry entered a period of leap forward development. To implement 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 transmission line 260000 km, 13.5 million KVA substation capacity.

Function of mini hdmi cable

Mini hdmi cable not only meet the highest quality 1080P resolution, but also support DVD Audio, the most advanced digital audio formats, support for eight-channel stereo 96kHz or 192kHz digital audio transmission, but with only one HDMI cable, eliminating the digital audio cable. Meanwhile HDMI standard has extra space can be used in future upgrades of audio and video formats. Sufficient to meet a 1080p video and an 8-channel audio signals. And because a 1080p video and 8-channel audio signal is less than the demand for a 4Gbps, HDMI therefore there is a great margin. This allows it to be connected with a DVD player, cable receiver and PRR. Alsomicro usb cable supports EDID, DDC2B, and therefore has a HDMI device has a "plug and play" feature, automatically "consultation" between the source and display devices, automatically selects the most appropriate video / audio formats.
  HDMI and DVI interfaces, compared with DVI Mini HDMI cable  nterface, smaller volume, and can simultaneously transmit audio and video signals. dvi cable ength can not exceed 8 meters, otherwise it will affect the picture quality, but HDMI can transmit as far as 15 meters. As long as a mini hdmi cable can replace up to 13 analog transmission line, a home entertainment system can effectively solve the tangled mess behind the connection problem.

Storage method of cable

Cable if stored for a long time, according to the position of the cable, should make the following considerations:
1, under the eaves. Cable only in not exposed to direct sunlight or ultra high temperature, standard LAN cables can be applied, recommend the use of pipeline.
2, external wall. Avoid direct sunlight and man-made damage to the wall.
3, in the pipeline (plastic or metal). As in the pipe, pay attention to thermal damage and metal pipe plastic pipe.
4, application of suspension / overhead cat5e cable . Considering the cable sag and the pressure, to adopt what kind of binding mode, cable is directly illuminated by the sun.
5, directly in the underground cable trench laying, the environment is the control of the minimum range. cat5e ethernet cable  trench installation must be periodically dry or moist degreeexamination.
6, the underground pipeline. In order to facilitate future upgrades, replacement of cables, and surface pressure and the surrounding environment isolation, auxiliarypipe isolation, auxiliary pipeline is a better method. But don't expect the pipeline will always keep dry, it will impact on the cable type selection.

Technological characteristics of cable

(1) process flow and equipment layout of production
Production workshop of equipment must be according to the requirement of products and reasonable process emissions, the half finished product of each stage, orderly transfer. Device configuration to consider differences in the production capacity of the production efficiency of the balance, some devices may be configured to two or more,to make the production line's production capacity to balance. Thus the reasonable selection of equipment combination and production site layout, must to balance considering according to products and production capacity.
(2) the organization of production management
Production organization and management must be reasonable and scientific, strict and meticulous, careful and accurate, the operator must be strict in one's demands,according to the requirement of process execution, any link problems, will affect the process smooth, affecting the quality of products and delivery. Especially in multi core cat6 LAN cable , a line on the basic unit of length or shorter, or quality problems, then the whole cable will be insufficient length, scrap. Conversely, if a unit length is too long, it must be off the waste.
(3) quality management
The mode of production of large length of continuous superposition and combination,so that the production process of any link, instantaneous point problem, affect the whole cable quality will. Quality defects occurred in the inner layer, but not found in time to stop production, so the loss caused by the. Because the wire and cat6 patch cable production is different from the assembled products, can be disassembled and replaced the other; any part or process quality problems of wires and cables, is almost unable to restore and remedy for this cable. After the treatment is very negative, not cut short is degraded, or scrap the whole cable. It can not be opened again.
Wire and cable quality management, must run through the entire production process.Quality management and inspection department to the whole production process of tour inspection, operation self checking, process under the mutual inspection, this isto ensure the product quality, an important guarantee to improve the economic efficiency of enterprises and measures.
