I Appendix A: Current Carrying Capacity of Aluminum Alloy Cables and Conversion Factors
A.1LetterofPresenta
This appendix applies to three-core and multi-core cables for load conduction currents in three-phase systems.
The current-carrying capacity data in this sectionapply toaluminum alloycables featuring aluminum alloy conductors,cross-linked polyethylene insulation,and polyvinylchloridesheathing.Thearmoredconfiguration for 0 . 6 / 1 \ \mathsf { k V } armored aluminum aloy cables employs an interlocking aluminum alloy armor strip,while that for 3.6/6-26/35 kVarmored aluminum alloy cables combines an interlocking aluminumalloy armor strip with a dual steel strip armor.
Thedata in this section are sourced from the National Building Standard Design Atlas 10CD106 'Aluminum Alloy Cable Installationand Layout,"provided solely for user reference.
For single-core cablesarranged in a planarconfiguration,the center-to-center spacing is twice the cable's outerdiameter.
For thecurrent-carrying capacity of 0 . 6 / 1 \ \mathsf { k V } cables,the referenceair temperature is 2 5 ^ { \circ } { C } ; thereference soiltemperatureis 2 5 ^ { \circ } { C } ,withasoil thermal resistance coefficient of 1 . 0 \mathsf { K m } M .The burial depth is 7 0 0 ~ { {mm } } #
Forthe current-carrying capacityof 3.6/6-26/35kVcables,the referenceairambient temperature is 2 5 ^ { \circ } \mathsf { C } 1 thereference soil ambient temperature is 2 5 ^ { \circ } \mathsf { C } ,withasoil thermal resistance coefficient of 2 . 0 ~ \mathsf { K } { * } \mathsf { m } N .The burial depth is 7 0 0 ~ { {mm } } #
The following laying methods are available:
E--Applied to naturally convective air.
C—The cable shallbe laid in horizontal or vertical perforated-free trays,installed on wooden walls,or directly embedded in brick or stone walls (with a wallthermal resistance coefficient not exceeding 2 . 0 \mathsf { K } { * } \mathsf { m } M 1
D1-The cable is installed within the soil conduit,with the soil thermal resistance coeficient set at 2 . 5 1 \mathsf { K } m/W for dry sandy soil (accounting for soil moisture migration).The burial depth is 7 0 0 ~ { {mm } } #
D2-The cable is directly buried in the soil,with thesoil thermal resistance coeficient set at 2 . 5 \mathsf { K } { * } \mathsf { m } M for Iry sandy soil (accounting for soil moisture migration).The burial depth is 7 0 0 ~ { {mm } } #
When the ambient temperature for cable installation inair differs from the values specified in the table,refer o Table A-1 for the current-carrying capacity correction factor.
Whentheambient temperature for cable installtion insoil differs from the values specified in the table, refertoTableA-2forthecurrent-carryingcapacitycorrection factor.
Thecurrent-carrying capacity reduction factors for bundled cable installations in electrical systems are showninTableA-3andTableA-4.
Thecurrent-carying capacity correction factor formulti-circuit clustered cable installations in soil is shown in Table A-5.

Appendix B
Transportation and Storage
The transportation and storage of cables shall comply with the following requirements:
The transportation and storage of cables shall comply with the following requirements: a) Cables should not be stored outdoors,and cable reels should not be placed flat.
a) Cables should not be stored outdoors,and cable drums must not be laid flat;
b)During transportation,cable reels containing cables should not be thrown from heights,and cables should not be subjected tomechanical damage.
b) During transportation,cable drums must not be dropped from heights,and mechanicaldamage to cables should be prevented;
c)Whenlifting packaging items,multiple rees should not belifted simultaneously.On transportation vehicles such as trucks and ships,cable reels must be securely positionedand fixed using appropriate methods to prevent collision or overturning.
c)When hoisting cable packages, multiple drums shallnot be lifted simultaneously.During transportation by vehicles or vessels,cable drums must be positioned stably and securely fastened using appropriate methods to prevent mutual collisions or overturning.
Precautions for Cable Procurement CableOrderingPrecautions
When purchasing cables,to ensure youobtain high-quality products that meet your project requirements,we advise you to adhere to the following standard details when specifying your procurement needs:
When purchasing cables,to ensure that you obtain high-quality products that meet theproject requirements,we remind you topayattention to the following standard detailswhenexpressing your procurement needs:
1.specifycable type:Accuratelyidentifythecabletypebasedonitsapplicationand characteristics.For example,if aflame-retardantcableisrequired,clearlylabelitas "Flame-retardant ClassA"(ZA)or"Flame-retardant Class B"(ZB).
Specify Cable Type:Please accurately designate the cable type based onitsintended useand characteristics.For example,ifflame-retardantcablesarerequired,pleaseclearlyindicate"Flame-retardant ClassA" (ZA),"Flame-retardant Class \boldsymbol { \mathsf { B } } ^ { \prime \prime } (ZB),etc.
2.Conductor material: specify the conductor material for the required cable,such ascopper conductor (T), aluminumconductor (L),oraluminumallyconductor(LH).Unlessotherwise specified,copperconductorcableswillbe provided by default.
Conductor Material: Please specify the conductor material of the cable,Such as copper conductor (T),aluminum conductor (L),or aluminum alloy conductor (LH).If not specifically indicated,we wil provide copper conductor cables by default.
3.Insulationand sheath materials:Please specifyindetail the insulationand sheath materials required for the cable,suchaspolyinylchlorideinsulation(V),ro-linkedpolyethylene insulation(YJ),orpolyvinylchloridesath(V).
Insulation and Sheath Materials:Please provide detailed information on the insulationand sheath materials of the cable,such as polyvinyl chloride (PVc) insulation (V),cross-linked polyethylene (XLPE) insulation (YJ),PVC sheath (V),etc.
4.Armoring requirements:If the cable requires armor,specify the armor type,suchas doublesteel tape armor (2) or fine round steel wire armor (3).
Armor Requirements:If armoring is required for the cable,please specify the type of armor,such as double steel tape armor (2),fine round steel wire armor (3),etc.
5.External sheath:If thecablerequiresanexternal sheath,specifythematerial,suchaspolyvinylchloride(PVC) sheath (2) orpolyethylenesheath (3).
Outer Sheath:If an outer sheath is needed for the cable,please indicate the material of theouter sheath, such as PVC outer sheath (2) or polyethylene outer sheath (3)
6.Dimension specifications: Please provide the nominal cross-sectional area of the cable (e.g., 1 . 5 \mathsf {mm } 2 , 2 . 5 \mathsf {mm } ^ { 2 } 0 and the required length.
Size Specifications:Please provide the nominal cross-sectional area of the cable (e.g.,1.5mm2,2.5 \mathsf {mm } ^ { 2 } )and the length requirements.
7.Performance Requirements: Based on the actual application environment,specify the performance standards that the cable must meet,such as temperature resistance rating,voltage resistance rating,etc.
8.Special requirements:If the cable has specific application requirements—such aswater resistance,oil resistance,acid/alkali resistance,or wear resistance—please specify these clearly during procurement.
Special Requirements:If the cable has special application requirements,such as water blocking, oilresistance,acidand alkali resistance,wearresistance,etc.,please clearly statethese requirements when purchasing.
9.Quantityand Delivery Schedule:Please provide therequired quantityof cablesandtheexpecteddelivery date so wecan betterarrange productionand logistics.
Quantity and Delivery Schedule:Please provide the quantity of cables required and thedesired delivery schedule so thatwe can better arrange production and logistics.
10.Quality Certification:Please specifywhethertherequired cables need to meet specific qualitycertifications,such aslSOcertification.Detail tis informationinyourpurchaseordertoensurewecanprovidecable products thatmeetyour requirements.If you have any questions, please feel free to contact us.
Quality Certification:Please indicate whether the cables need to pass specific quality certifications, suchas ISO certification,etc.Please list theabove information indetail in thepurchase order to ensure that we can provide you with the cable products that meet your requirements.If you have any questions, please feel free to contact usatany time.
