Aluminum alloy electrical conductivity is the most commonly used reference materials copper IACS 61.5%, carrying capacity is 79% better than that of pure copper, aluminum standard. But in the same volume, aluminum alloy actual weight is around 1/3 copper. According to the calculation, meet the same conductive performance of the premise, the same weight of aluminum alloy cable length is two times of the copper cable. Therefore, the same carrying capacity of aluminum alloy and the weight of the cable is approximately half the copper. Using aluminum alloy cables instead of copper, can reduce the weight of the cable, reduce the installation cost, reduce equipment and cable wear, making installation easier.

How to install underground cable

It is not particularly hard to run underground cable to a detached garage or other outbuilding, especially if you have some basic wiring experience. If you just need to add some lighting and a few outlets, you can tap into an existing circuit in the house. For bigger electrical needs, though, plan to run a circuit or two from the service entrance panel to a subpanel mounted in the garage. If you are not sure what your future electrical needs might be in the garage, install the subpanel.

You may want to hire an electrician to handle wiring connections in the house and garage. But you can still save a lot of money on the project by digging the trench yourself and installing underground conduit.

Use the Right Type of Cable

When running underground cable, the only kind of cable to use is type UF (underground feeder) electrical cable. 

Types of Conduit

When running electrical wiring underground, type UF cable should be routed through rigid conduit. There are two types of conduit that can be used for underground cable. Schedule 40 PVC conduit is the most common and affordable choice. This type of conduit is gray, and it is joined with PVC cement. You can also use rigid metal conduit, although it will cost significantly more. Do not use thinwall (EMT) conduit underground. Use conduit that is at least 3/4-inch wide. 

PVC conduit needs to be buried at least 18 inches deep unless it will be covered by concrete, in which case it can be buried 12 inches deep. Rigid metal conduit can be buried as little as 6 inches deep, with or without a concrete cap. Be sure to check with your local code before you start installing underground cable.

Dig a Trench

Use a trenching shovel to dig a narrow channel from the house to the garage. If you have to dig a long trench, you may want to consider renting a trenching machine for this job. 

Install the Conduit

PVC conduit can be cut with a hacksaw or PVC saw. Dry fit all of the pieces along the entire run. Join the pieces of conduit with PVC cement. Run type UF cable through the conduit, and then make the necessary connections in the house and garage. Always check your local building code before you begin running underground cable.

With underground cables the individual conductors, being insulated, can be closer together, leading to greater cancellation and lower fields. However, unless they are buried very deeply, they can also be approached more closely, leading to higher fields. Overall, ground-level magnetic fields from underground cables fall much more rapidly with distance than those from a corresponding overhead line, but can actually be higher at small distances from the cable.

Jack knowledge about cable:Safety requirements of the cable

In the power transmission , especially in modern super high voltage and high voltage power transmission process , the security is often a very important issue . It plays an important role in the power transmission cables which security demands? Power cable companies who generally have the following five points.

1 cable cross each other , the high-voltage cables should be below the low-voltage cables . If one of the cables around the crossing point within the range of 1m or wear protective tube separated by a partition , the minimum allowable distance of 0.25m.

2 cables with heat pipe close to or intersect , if insulation measures , a minimum distance of parallel and intersecting 0.5m respectively and 0.25m.

3 cable railway or road intersection should wear protective tube to protect the pipe should extend beyond 2m rail or road .

4 cables from the building foundation should be able to ensure that the cable is buried outside the building bulk water ; cable into the building should wear protective tube , the tube should be beyond the protection of bulk water outside the building .

5 should distance between the ground directly buried cables and grounding devices generally 0.25 ~ 0.5m; direct buried cable burial depth , generally not less than 0.7m, and should be buried in the permafrost .

Cultivate the world brand is the route one must take to enhance the international competitiveness Chinese cable industry

In April 11th, state quality inspection administration director Chinese Zhi Shuping at the Boao forum for Asia 2014 said the first "brand of Asia" points on the BBS, the past 30 years, "China manufacturing" all over the world market, but Chinese brand in the international competition is still in the vulnerable. In 2013, there have been 96 China enterprises to enter the "wealth" list of the world's top 500 enterprises, but a few years into the "world brand 100 strong" and "best global brands list" China brands are scanty.

An important symbol of industry powerful is has a number of world-class brand of large enterprises, which will play an important role in many aspects: to enhance the overall competitiveness of national industry standards, improve the international counterparts in the discourse right, enhance the country's export capacity, to enhance the national brand awareness, make it easier for enterprises to obtain trade at a premium in the international trade.

The annual output value of Chinese wire and cable industry trillion yuan in line with the image China the vigorous development of the country, but in recent years, thousands of companies from the ground situation, the lack of a sufficient number of world-class giant enterprises are to a certain extent constraints of industrial development. Therefore, the community generally believes that the industry is big but not strong. According to cable network (cableabc) reporter understanding, the Far East cable led the domestic top five leading cable enterprises accounted for the national market share of less than 10% of the sum of the cable. While the French top five cable company turnover accounted for the country's market 90%; America before the ten cable companies accounted for the country's 67% of the market; Japan's seven cable companies won the 86% of the national market. While the global 1/4 wire and cable market, has been Prysmian, Alcatel, USA general cable, wire and cable giants occupy 8.

Dongguan Anmei Lubrication Technology Co. Ltd. cable technology department director Feng Jun in 2014 Chinese (Changzhou) electric wire and cable equipment and materials exhibition received cable network (cableabc) said when interviewed by reporters, the domestic cable industry, although the enterprise quantity many, but the annual output value of over 10 billion yuan less, the world famous brand enterprise is less, while the developed countries not.

"A brand is not easy, not easy to brand." Huadong power cable company CEO in the second China (Wuhu) electric wire & cable exposition and the quality of the products the summit lamented. The domestic cable companies in the promotion for the road world class brand, is also faced with domestic trouble and foreign invasion "".

On the domestic, disorderly market competition compression of the domestic enterprise market so as to restrict the birth of the world brand. "Many manufacturers in order to reduce the cost of the Copperbelt of choice, and strip thickness will affect the service life of the cable." General manager, Henan Shenghua wire Co. Ltd. senior economist Zhang Laicheng, combined with years of experience in dealing with the cable companies, the problems existing in the reality.

Bad money drives out good phenomenon in cable industry is not uncommon, "many domestic cable companies in order to more for orders, competing to keep the prices down, leading to the high and low prices by 30% to 40%, or even more, and sometimes even less than the price of materials." Far east Holding Group chairman of the board Jiang Xipei to cherish an undying means low price or the lowest bid this illegal competition.

On abroad, Prysmian, Alcatel, American general cable and other international giants to carve up the China cable market in the heart of the obvious. For most China enterprises, because its management, technology, products, services and other than these foreign giants are not a small gap, so in the confrontation of seldom win, especially in the "tall" submarine cable and other products. This situation not only directly affect the domestic enterprise product market share, but also to some extent a booster of small enterprise more the use of illegal means to compete for the market.

Chinese cable industry needs more nurturing world brand in the process from big to strong in. From the government a series of reform measures, will be for the domestic cable industry cultivate the world brand to add a lot of confidence. Of course, Chinese cable industry and enterprise also needs to purify the market environment, improve the technical level, enhance the ability of product research and development, strengthen management capabilities and efforts.
