Daga yadda ake amfani da aluminium kafin steel a cikin ƙirƙira kayan kable?
Amfani da aluminum kafin yake da copper (baba da haka steel, domin steel ba a yi amfani da shi a wajen kawo ciki masu wire conductors) a cikin ingantaccen wires tana da dalilai daban-daban. Idan koyar da aka bayar ya ce "steel," saboda wurin, wannan bayani ya nuna cewa baki daya da ke amfani da aluminum a matsayin material da ake amfani da shi a matsayin conductor na lines na power transmission. Hakan ne dalilan da ake amfani da aluminum a matsayin material na conductor:
Efficiency ta Cost (Cost Efficiency)
Kadan Yawan Kirkiro: A cikin copper, aluminum yana da kirkiro yawan. Saboda networks na power transmission suna bukatar wire zuwa babban fadin, amfani da aluminum zai iya haɗa kadan zuwa mafi kirkiro.
Economical: Don projects na transmission na tsawon lokaci, albashi na cost ta aluminum yana cikin jin da suka fi sani.
Lightweight (Lightweight)
Yawan Da'awa: Aluminum yana da density kimanin da ya kai da copper, wanda yake da aluminum cables zai zama kadan da dukkan copper cables na musamman da take. Wannan kadan yana haɗa abubuwan da kuma kadan da ake amfani da su a matsayin transportation da kuma da'awa.
Kadan Ta Structural Load: Kadan yana haɗa abubuwan da ake amfani da supporting structures (kamar towers da poles), wanda yake da ƙarin kadan da ake amfani da su.
Good Conductivity (Good Conductivity)
Conductivity: Idan aluminum yana da conductivity kadan da copper (conductivity na copper yana cikin 100%, wanda ya kai da aluminum yana cikin 61%), aluminum yana da conductivity da ya fi kyau don applications na power transmission.
Compensation Measures: Kadan conductivity ta aluminum zai iya haɗa da increasing the cross-sectional area of the aluminum wire, wanda yake da performance levels similar to those of copper wires.
Corrosion Resistance (Corrosion Resistance)
Surface Oxide Layer: Aluminum yana da oxide layer da ya fi shi a air, wanda yake da further oxidation and corrosion, wanda yake da good corrosion protection.
Kadan Ta Maintenance Costs: Relative to copper, self-protective properties ta aluminum yana haɗa kadan ta maintenance costs.
Mechanical Strength (Mechanical Strength)
Composite Materials: In some cases, to enhance the mechanical strength of aluminum wires, alloys or embedding high-strength steel wires within the aluminum (such as ACSR - Aluminum Conductor Steel Reinforced) can be used. This maintains the conductivity of aluminum while increasing mechanical strength.
Flexibility: Aluminum yana da ductility da toughness, wanda yake da ita kadan da ya ci kawo a bending and stretching processes.
Environmental Considerations (Environmental Considerations)
Abundant Resources: Bauxite, ore from which aluminum is derived, is more widely distributed globally and easier to mine and refine compared to copper ores.
Recycling: Aluminum yana da recycling value da ya fi kyau, kuma zai iya amfani da shi a wuri da yawan waɗanda ba a ci kawo ba.
Policy Support (Policy Support)
Government Support: Some countries and regions may implement policies encouraging the use of aluminum wires to promote the development of the domestic aluminum industry or to reduce transmission costs.
Coefficient of Thermal Expansion (Coefficient of Thermal Expansion)
Adaptability: Aluminum yana da coefficient of thermal expansion da ya fi shi da copper, wanda yake da ita kadan da ya ci kawo a temperature variations. Through proper engineering design, this can be utilized to adjust the tension in the wires.
Summary
In summary, the main reasons for using aluminum as a conductor in power transmission lines are its cost-effectiveness, lightweight nature, good conductivity, corrosion resistance, mechanical strength, and environmental benefits. These factors make aluminum a widely-used conductor material in power transmission. Of course, in specific applications where higher conductivity and better stability are required, copper remains an indispensable choice.
