AAC All Aluminum Conductor aac  LARKSPUR conductor

 

 

  AAC ,AAAC and ACSR condcutors have been widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.

 

Conductor Conductors are made from electrolytic grade aluminium conforming to IEC STANDARD, and are compact circular or compact shaped.

Insulation HMT XLPE insulated cables are specially made high grade cross-linked polyethylene for insulation by extrusion process.

Core Identification

Different colours identify the cores

Laying up In multi-core cables, cores are laid up as per the above colour scheme, interstices are filled wherever necessary to make the laid up cores circular.

 

Inner Sheath Laid up cores are bedded over with thermoplastic material for protection against mechanical and electrical damage.

 

Armouring Armouring is provided over the inner sheath to guard against mechanical damage. Armouring is generally of galvanized steel wires or strips (In single core cables used in AC system armouring is by non-magnetic hard aluminum wires/strips). Round steel wires are used where the diameter over the inner sheath does not exceed 13mm. Above 13mm, flat steel strip armour is used. Round wire of different sizes can be provided against specific request.

 

Outer Sheath Specially formulated heat resistant black PVC compound confirming to the requirement of Type ST-2 of IS:5831-1984, extruded to form the outer sheath. HMT XLPE offers a specially formulated Flame Retardant Low Smoke Compound(FRLS) for outer sheath used in fire hazardous environment.

 

Tests In addition to all tests as required by IS:7098 Part-1, HMT XLPE Cables are subjected to a number of in-house tests at every stage of production. Incoming raw material is also tested thoroughly to ensure consistency of quality.

aac marigold conductor AAC(All aluminum conductor) are suited for overhead power line. We can supply this conductor according to different recognized standards, such as IEC61089, BS215, BS EN 50182: 2001, STM B231, CSA C49, DIN480201, JIS C3109, customer special specification also can be satisfied. ACSR or ACSR cable or ACSR conductor used for Overhead electrical distribution and transmission lines for distributing power Applications Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
Construction Aluminum alloy 1350-H-19 wires, concentrically stranded about a steel core. Core wire for ACSR is available with class A, B, or C galvanizing; ""aluminized"" aluminum coated (AZ); Or aluminum-clad (AW). Additional corrosion protection is available through the application of grease to the corer or infusion of the complete cable with grease.
Specifications ACSR bare conductor meets or exceeds the following ASTM specifications: aac marigold conductor B-230 Aluminum Wire, 1350-H19 for Electrical Purposes B-231 Aluminum Conductors, Concentric-Lay-Stranded B-232 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR) B-341 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ) B-498 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ) B-500 Zinc Coated and Aluminum Coated Stranded Steel Core for Aluminum Conductors, Steel Reinforced (ACSR)
Notes

aac marigold conductor Resistance is calculated using ASTM standard increments of stranding and metal conductivity of 61.2% IACS for EC (1350) and 8% IACS for steel. AC (60Hz) resistance includes current dependent hysteresis loss factor for 1 and 3 layer constructions. Current ratings are based on 75oC conductor temperature, 25oC ambient, 2ft/s wind, 96/watts/sq. Ft sun, 0.5 coefficients of emissivity and absorption.
