National Cables - Quality Standard

Quality is inbuilt from raw materials to final product. Quality is checked and controlled and inbuilt in each process.

Since quality is the buzz word today & each customer/consumer wants it in totality. Our quality policy & work philosophy stresses towards total customer satisfaction. We have well defined interdepartmental as well as intra Departmental Network Blocks where complete monitoring of job works is done. A well trained staff/Dedicated sales /Excelled production force all strive continuously delivering better services to the customer. An ISO-9002 certification is an affidavit to it which consolidates our verdict for quality.

Description Design

Cable with Copper / Aluminium Conductors PVC insulated colour coded cores laid extruded PVC inner sheathed overall PVC sheathed armored / unarmored cables.

Quality Control

A highlight of National Cables is its emphasis on Quality Control, Quality Audit and Quality Assurance in the spheres of manufacturing activities and service, i.e. from RAW MATERIAL TO FINISHED PRODUCT to CUSTOMER SUPPORT SERVICES.

Electrolytic Copper & Aluminum ensures longer life for conductor. Bunching/twisting of ministrants as per international standards.
  • Proper annealing gives softness & flexibility.

  • Insulation -grade PVC stands high temperatures.

  • Higher DI-electric strength insulation used.

  • Weather proof sheathing/insulation material.

  • Grease/Oil resistant properties.

  • Voltage fluctuations don't affect.

  • Resistant to fire hazards.

  • Self fire-extinguishing & flame proof cables.

  • Rigid quality controls conforms to-specification.

  • Chemicals and microbiological attacks don't affect.

  • No damage due to severe bending while laying.

  • Immune to fluctuations in temperatures.

  • Fire Insurance approved.

Testing is a very important part of cable manufacture and all raw materials and finished cables must be thoroughly tested to ensure the quality of cables. National Cables has a well equipped test fields and electrical, mechanical and chemical laboratories capable of carrying out all tests which are required as per relevant specifications. The most modern testing equipment is installed in these laboratories.

The various tests carried out on PVC cables are classified in three different groups:-

(1) Routine Tests (2) Type Tests and (3) Acceptance Tests

Routine Tests

The following tests constitute Routine Tests which are carried out on each and every length of cable before it leaves the factory.

(A) Conductor Resistance Test

The tests ensure that conductor resistance is within the specified limit, thereby verifying that the continuity of conductor is maintained throughout the cable length and that the conductor has the required electrical section D.C. resistance,  is measured at room temperature and is then corrected to standard reference temperature of 20°C.

(B) High Voltage Test

This test ensures that insulation will safely withstand the rated voltage with permissible variation in normal operation.

Type Tests

These tests are carried on samples taken from each production lot. They are carried out to prove conformity as regards the general qualities and design to the specification of particular type of cables.

Delivery Lengths

500 Meters plus or minus 5% in the cables of overall diameters upto 29 mm and 250 Meters or less in cables having overall diameters of 30 mm and above.

Our cables are packed in sturdy non-returnable wooden drums. The drums are heavy duty and made for transit handling and storage.
  • We have IS Certification for marking our cables with ISI mark covering cables conforming to IS: 1554 (P-I) 1988.
