Quality Control

2 Clam Aluminum Conductor Triplex Overhead Service Drop Cable

Raw Material Test

Incoming materials for 2-2-2 Clam Aluminum Conductor Triplex Overhead Service Drop Cable pass strict verification. 1. 1350-H19 aluminum wire rods undergo spectrometry for alloy purity, conductivity testing (>61% IACS), and mechanical evaluation (tensile, elongation) per ASTM B-230/B-233. 2. Neutral messenger components (ACSR steel core) check galvanization adherence, strand integrity, and tensile strength per ASTM B-232/B-498. 3. XLPE pellets tested for melt index, density, thermal aging performance, tensile/elongation after oven aging, and UV stabilizer content. 4. Full supplier documentation reviewed alongside random sampling for defects or inconsistencies. Rejected lots returned; approved materials tagged for batch traceability throughout manufacturing.

Process inspection

In-process quality checks for 2-2-2 Clam Aluminum Conductor Triplex Overhead Service Drop Cable maintain precision. 1. Stranding monitored for accurate concentric lay, strand count, and no overlaps in #2 AWG conductors/neutral. 2. Insulation extrusion: XLPE thickness continuously gauged (nominal 0.050–0.060 inches), temperature/speed logged for proper cross-linking. 3. Twisting: Triplex assembly verified for balanced configuration, correct lay length, and insulation protection. 4. Inline high-voltage spark detection identifies any pinholes or faults. 5. Regular sampling for resistance, visual defects, and dimensional accuracy. Non-conformances result in immediate corrective actions and segregation to uphold product integrity.

Finished Product

Completed 2-2-2 Clam Aluminum Conductor Triplex Overhead Service Drop Cable receives thorough final QA. 1. Conductor DC resistance and stranding confirmation per ASTM standards. 2. Insulation resistance and AC withstand voltage testing (no breakdown at specified levels). 3. Physical measurements: insulation thickness, eccentricity, tensile/elongation of all components. 4. Ampacity validation against tables (≈150A). 5. Comprehensive visual check for marking accuracy ("Clam", specs, standards), surface condition, and no damage. 6. Flexibility/coiling tests performed. Full test documentation generated; passing products certified, labeled, and approved for shipment.

Application

Used primarily for overhead service entrances from utility transformers/poles to residential/commercial weatherheads. Suitable for single-phase 600V distribution in rural and urban installations, pole-to-pole secondary feeds, and reliable power supply in varied climatic conditions.

FAQ From Customers

What are the advantages of power cables and overhead lines?

(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people;
(2) The maintenance workload is small and frequent inspections are not required;
(3) No need to erect towers;
(4) Help improve power factor.

Which aspects should be considered when choosing the cross section of a power cable?

(1) The long-term allowable working current of the cable;
(2) Thermal stability once short circuited;
(3) The voltage drop on the line cannot exceed the allowable working range.

What are the measures for cable fire prevention?

(1) Use flame-retardant cables;
(2) Use fireproof cable tray;
(3) Use fireproof paint;
(4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.;
(5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.

What should be paid attention to during the transportation and handling of cables?

(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat.
(2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.

What inspections should be carried out for the acceptance of cable lines?

(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear;
(2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements;
(3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements;
(4) Good grounding;
(5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted;
(6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.

How many projects can cable engineering be divided into?

(1) Construction site transportation: including the loading and unloading, transportation and empty vehicle return journey of engineering materials from the warehouse to the construction site.

What tests and inspections should be carried out on power cables before laying?

Before laying, check whether the type, specification and length of the cable meet the requirements and whether there is external force damage. Low-voltage cables use a 1000V megohmmeter to remotely measure the insulation resistance, and the resistance is generally not less than 10MΩ. High-voltage cables use a 2500V megger to measure the resistance. Generally not less than 400MΩ.

(6) Rubber insulated power cables.

What are the requirements for the fire blocking of cable holes?

For larger cable penetration holes, such as the cable penetration floor, etc., when using fireproof blocking materials to block, according to the actual situation, first coat four to six layers of fireproof paint on the cable surface, the length is about 1.5m below the hole, and then use fire-resistant The material is processed into a board-supporting fire-proof blocking material with a certain strength to ensure that it is firm after being blocked and is easy to disassemble and assemble when the cable is replaced.

At five evenly distributed points on the circumference of the sheath, measure the outer diameter of the sheath and its average value. The average outer diameter is the outer diameter of the sheath.

How to connect copper core cables with different cross-sections?

Copper core cables with different cross-sections can be connected by open-back weak copper pipes and connected by soldering, or pure copper rods can be connected into copper pipes according to different cross-sectional requirements and connected by crimping.
