ABC cable overview,everything you need to know

What is ABC cable?

ABC cable has another name Aerial Bundled Cable that mainly available for overhead power distribution. The ABC cable provide higher safety and reliability,lower power losses and system economy by reducing installation, maintenance and operating costs. 

The cable are very available for rural and specially available for installation in difficult terrains such as hilly areas,forest areas,coastal areas. In developing urban,aerial bundled cable is also the best choice.

The cable are mainly available for urban distribution networks construction. Not only it can overcome many of the disadvantages and operational problems of bare wire, and also more inexpensive.

The structure of ABC cable

XLPE/HDPE insulation is laying on the periphery of the aluminum conductor.XLPE (cross-linked polyethylene) is black, and that is against deterioration caused by exposure to direct sunlight and UV radiation. XLPE is cross-linked low-density polyethylene, that is made thermo set by special formulation from base base polymer of thermoplastic.

Conduction insulation is identify with ridges for phase identification.

Low voltage ABC cable

This cable is made of several of insulated conductors, bundled and wrapped together tightly.the rate maximum current is v or lower.aerial bundled cable have an operating temperature range of -40 to +80, and can be installed in temperature as -20.
Our low voltage cable is manufactured in according with range of national standards.standard low voltage overhead bundled cable meet:IEC 、BS 、DIN 、ASTM B399、BS EN、NFC33-209.

Medium voltage ABC cable

This higher voltage cable is sheathed with high-density polyethylene(HDPE).we supply medium voltage ABC cable,in voltage of 6.35/11kV、12.7/22kV and 19/33kV .

Duplex cable/triplex service drop cable

This cable carry the load of 120v that for overhead application.for example street lighting.these Duplex cable/triplex service drop cable use XLPE for insulation material.the mainly composition is -H19 aluminum twisted concentrically for conductor material.its neutral core is made up of aluminum alloy .

ABC cable application environment

Aerial bundled cable can be available of:
. As an alternative to bare conductor rural areas,forest areas and other areas,and narrow streets with limited space.
. As an alternative to bare conductor, the stability of voltage is very important.
. In hilly areas where the installation cost of overhead lines or underground cables becomes very high.
. As a reinforcement to existing systems without adding voltage.
. Used for temporary replenishment.

The advantage of ABC cable

· High security:
Improved reliability in comparison with both bare conductor overhead systems and underground systems. Insulated conductors prevent accidental contact.

· Low maintenance cost:
· Wide coverage:
· To prevent short circuit:
· Affordable price:
·Easily detect failures:
Reduce the maintenance and necessary inspection of the line.

· Easy installation:
Simpler installation, as crossbars and insulators are not required.

Increasing demand for electricity in the emerging and developed countries, backed by increasing investment in infrastructure, is expected to drive the cables market globally. We can provide you the best aerial bundled cable price, you can contact TANO CABLE.

What are Overhead Cables?

Overhead cable, known as overhead insulated cable, is an overhead conductor equipped with an insulation layer and a protective sheath.
It is a special cable manufactured by a production process similar to cross-linked cable and is a new transmission method between overhead conductors and underground cables.

Overhead cables are single-core, according to their structure can be divided into hard aluminum wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel or aluminum alloy core support structure, and self-supporting three-core stripline structure.
The core can be hard aluminum or hard copper wire.

Advantages and Disadvantages of Conductors

Advantages

• Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.

• Can stand in close proximity to trees/buildings and will not generate sparks if touched.

• Little to no tree trimming is necessary.

• Simpler installation, as crossbars and insulators are not required.

• Ease of erection and stringing, less labor intensive, fewer construction resources needed.

• More aesthetically appealing.

• Can be installed in a narrower right-of-way.

• At junction poles, insulating bridging wires are needed to connect non-insulated wires on either side.

  ABC can dispense with one of these splices.

• Less risk of a neutral-only break from tree or vehicle damage, increasing safety with TNC-s systems.

• Significantly improved safety for linespersons, particularly when working on live conductors.

• Electricity theft is made harder, and more obvious to detect.

• Less required maintenance and necessary inspections of lines.

• Improved reliability in comparison with both bare conductor overhead systems and underground systems.

  What Are the Benefits of Customized Computer Connectors and Cables?

  Insulated conductors prevent accidental contact and supply can be maintained temporarily in the event of a suspension system collapse.

Cable Disadvantages

• Additional cost for the cable itself.

• Insulation degrades due to sun exposure, though the critical insulation between the wires is somewhat shielded from the sun.

• Shorter spans and more poles due to increased weight.

• This can lead to much longer repair times for installations in hilly areas due to much higher line weights requiring bigger and more specialized equipment to repair.

• Older installations are known to cause fires in areas where falling large trees or branches regularly cause breaks in lines and or in insulation leading to short circuits which can then lead to burning insulation dripping to the ground and starting ground fires.

• Failure modes through punctures, electrical tracking, and erosion.

Disadvantages of Flexible Cable

• High Investment Cost

  As the outer sheath of the mineral cable is composed of seamless copper tubes, the overall copper content is much more than that of ordinary cables.

• The Joints are Susceptible to Moisture
  The insulation layer consists of mineral minerals, joints, and cable ends it is very easy to chemical reaction with the moisture in the air, and generate hydrogen minerals that can conduct electricity.

• Difficult Construction
  Mineral cable hardness and general cable compared to the high distribution box and bending within the bridge molding difficulties.
  

• The Construction Workload is Large
  Mineral cable where the specifications of more than 35mm are single-core cable, such as a 95mm cable, ordinary cable only 4 × 95 + 1 × 50 five conductors in the same outer sheath.

Coaxial Cable Advantages and Disadvantages

For the other most common cable, coaxial cable, the advantages far outweigh the disadvantages.
But it also has disadvantages that cable manufacturers cannot ignore when producing, and that is that coaxial cable is easy to cause a fault in the operation of the whole network down.
Compared to other cables, this is really a very troublesome point.
However, the advantages of coaxial cable, it is not only inexpensive, and easy to wire and install, but also has good resistance to electromagnetic interference, cable capacity of up to 10Mbps, and a long and durable life.

There are good and bad sides to everything, not that it's bad, just because it doesn't fit.
