Frequently Asked Questions from TANO CABLE

As an integrated cable and wire solution provider, TANO CABLE will offer customers a detailed guide for your cable selection needs based on rich experience. However, before this, we need customers present the unique application circumstances.

Let's talk about the advantages of both based on production and construction experience. 1. The advantages of aluminum core cables over copper core cables: 1) Low price: Copper pole is several times the price of aluminum pole, so aluminum core cable is much cheaper than copper core cable, economical and practical. 2) The cable is very light: the weight of the aluminum core cable is 40% of that of the copper core cable. The production material cost is greatly reduced. In terms of construction, the aluminum wire is light in weight, and the construction is convenient to save labor. Aluminum quickly reacts with oxygen in the air to form an oxide film, which can prevent further oxidation. Therefore, aluminum wire is a necessary material for high-voltage, large-section, and large-span overhead power transmission. 2. The advantages of copper core cables over aluminum core cables 1) Low resistivity: The resistivity of aluminum core cables is about 1.68 times higher than that of copper core cables.　　 2) Good ductility: the ductility of copper is 20-40%, the ductility of electrical copper is more than 30%, while aluminum is only 18%. 3) high strength: the allowable stress at room temperature, copper is 7~28% higher than aluminum. Especially the stress at high temperature, the difference between the two is even greater. 4) Anti-fatigue: Aluminum is easy to break after repeated bending, while copper is not easy. In terms of elasticity index, copper is also about 1.7 to 1.8 times higher than aluminum. 5) Good stability and corrosion resistance: The copper core is resistant to oxidation and corrosion, while the aluminum core is susceptible to oxidation and corrosion. 6) Large current carrying capacity: Due to the low resistivity, the copper core cable with the same cross-section is about 30% higher than the allowable current carrying capacity (the larger current that can pass) of the aluminum core cable. 7) Low voltage loss: Due to the low resistivity of the copper core cable, the same current flows in the same section. The voltage drop of the copper core cable is small. Therefore, the same transmission distance can ensure higher voltage quality; in other words, under the allowable voltage drop condition, the copper core cable can reach a longer distance, that is, the power supply coverage area is large, which is beneficial to network planning and reduces The number of power supply points. 8) Low heating temperature: Under the same current, the copper core cable with the same cross-section has much smaller heating value than the aluminum core cable, which makes the operation safer. 9) Low energy consumption: Because of the low electrical resistivity of copper, it is obvious that copper cables have low power loss compared to aluminum cables. This is conducive to improving the utilization rate of power generation and protecting the environment. 10) Anti-oxidation and corrosion resistance: The performance of the connector of the copper core cable is stable, and there will be no accidents due to oxidation. When the connector of aluminum core cable is unstable, the contact resistance will increase due to oxidation and heat will cause accidents. Therefore, the accident rate is much greater than that of copper core cables. Through our comparison, we can draw a conclusion that the advantages of copper core cables are far more than aluminum core cables. Simply put, aluminum core cables are not only cheap but convenient to handle. In terms of economic investment, aluminum core cables are the better choice. However, for long-term practicality, copper core cables are the better choice.

Welding cable usually comes with rubber insulation, typically either Neoprene or Ethylene Propylene Diene Monomer (EPDM) rubber, and is designed to be fire (small sparks), water, oil, and abrasion resistant.

1. Most of our products  are certified. 2. Our Lab staff will test the material and check the process card before production. 3. The O.D tester is testing all the time during production, and the production line is always under control. 4. The product will be tested by Lab staff after finishing production.

Flexible Cable applications are to withstand the extreme stress of flexing and motion. A few applications include: drag chain applications, applications with repetitive bending and torsion stress, machine tools, data processing equipment, robotics, assembly lines, automation networking, microprocessor and computer interconnects and many more.

Waterproof wire and cable research and development has been a problem in the main study, after many long and repeated experiments we can found that even if the insulating sheath is not broken, there will be some water or moisture seeped into the core of power cables. Thus, it is generally considered that improving three core waterproof cables to three single core waterproof cables structure is better when medium voltage power cables or low voltage power cables applied to real-life. We can produce cables based on the structure of single core medium voltage waterproof power cable, then stranding three single core cables instead of three core cables. Water-blocking effect of improved water proof power cable will be better, and the structure become simple, it is not only save water blocking and cost, but also improve the carrying capacity and heat dissipation potential of power cables on the other hand, ease of manufacture, and easier to install. The most important is to prevent the ingress of moisture inside the cable, keep dry insulated core, to further extend the life of the cable. Specifications of split-phase metal compartment power cables 1. Specifications of power cable core Conductor should be metallized or non-metallized annealed copper, aluminum, or aluminum alloy which consistent with GB/ T3956 type 1 or type 2, it also can be bare copper or metallization annealed copper conductor consistent with GB T3956 type 5, Insulation, metal shielding (if any), cabling, inner sheath (if any), the outer jacket to meet GB /T12706 relevant standards. 2. Specifications of split-phase metal sheath After the completion of phase metal sheath. we need test for cables inflate, the test should be met. cable filled 50-100KPa dry air or nitrogen, total length of the cable after the pressure equalization within 3h, the air pressure in the cable should not be reduced. 3. The integrated waterproof specifications of metal power cable Cable finished product soaked in water 72 hours then the case of the surface except the insulating structure, observe the surface should be dry Phase metal sheath water poof power cable manufacturing process is simple, all aspects of performance are more excellent, and it is suitable for medium and low voltage cable selection.
