Power Cable Manufacturing and Factory Testing Course – Istanbul (Turkey), 15–19 Nov 2026

Introduction:

Power cable manufacturing and factory testing is the engineering and quality verification discipline of producing insulated electrical conductors and confirming their mechanical and dielectric integrity prior to dispatch. This one-week course prepares engineering, quality assurance, and technical procurement specialists to construct an audit-ready Cable Manufacturing Quality Plan and Factory Acceptance Test Dossier. Delivered at practitioner depth through a structured inspection walkthrough methodology, delegates apply the International Electrotechnical Commission IEC 60502-2 standard for medium-voltage extruded power cable construction and material testing. Professionals master power cable manufacturing and factory testing with Blackbird Training Centre to deliver reliable transmission assets.

Course Objectives:

• Distinguish between copper and aluminium conductor performance by evaluating stranding compaction, direct current resistance, and thermal expansion properties under IEC 60228.
• Compare IEC 60502-1 low-voltage extrusion criteria versus IEC 60502-2 medium-voltage insulation specifications for shielded power cable assemblies.
• Apply IEC 60811 physical test methods to verify hot-set elongation, tensile strength, and thermal ageing limits of extruded cross-linked polyethylene insulation.
• Select continuous catenary vulcanisation or vertical continuous vulcanisation processing parameters to maintain insulation concentricity and eliminate micro-voids.
• Interpret high-voltage alternating current withstand, partial discharge extinction, and tan-delta dissipation factory test results to confirm dielectric integrity.
• Justify witness inspection hold points across manufacturing stages to construct a validated factory acceptance testing quality dossier.

Target Audience:

• Cable production specialists responsible for extrusion line operations who must decide between continuous catenary and vertical vulcanisation cooling profiles.
• Quality assurance inspectors responsible for non-destructive factory testing who must judge partial discharge waveforms against pass-fail thresholds.
• Electrical procurement engineers responsible for manufacturer compliance who must evaluate supplier raw material certificates and extrusion line capabilities.
• Asset integrity technicians responsible for cable pre-commissioning who must determine insulation resistance and sheath integrity before site energisation.

Conclusion:

Rigorous power cable fabrication and factory evaluation ensure that electrical distribution assets operate reliably under severe continuous operational stress. The curriculum clarifies the technical boundaries between copper and aluminium conductor behavior, low-voltage versus medium-voltage extrusion shielding requirements, and routine dielectric withstand tests versus material type qualifications. Designed for manufacturing engineers, quality assurance personnel, and procurement inspectors seeking practitioner competence, this course provides the technical expertise and structured inspection methodologies necessary to evaluate production lines and verify compliance against established international standards.

Frequently Asked Questions (FAQ):

What is power cable manufacturing and factory testing?

Power cable manufacturing and factory testing is the industrial process of drawing conductors, extruding polymeric insulation, applying protective armoring, and conducting dielectric and mechanical tests. It ensures medium- and low-voltage cables satisfy design limits, insulation resistance, and dielectric breakdown thresholds prior to site installation.

What is the difference between routine testing and type testing in power cable manufacturing and factory testing?

Routine testing is conducted on every manufactured cable length to detect manufacturing flaws using spark, conductor resistance, and high-voltage withstand tests. In contrast, type testing involves destructive laboratory procedures on sample specimens to qualify the cable design and raw materials before commercial production commences.

Which international standards govern power cable manufacturing and factory testing?

International Electrotechnical Commission standards govern the process, primarily IEC 60228 for conductors, IEC 60502-1 and IEC 60502-2 for low- and medium-voltage power cable construction, and IEC 60811 for material testing. Industry specifications such as AEIC CS8 establish additional electrical shielding and dimensional criteria.

Is this power cable manufacturing and factory testing course suitable for procurement and quality assurance inspectors?

Yes, this course is designed for quality assurance specialists and technical procurement inspectors who audit cable factories and witness factory acceptance tests. It equips delegates with the criteria needed to review material certifications, evaluate continuous vulcanisation lines, and verify factory acceptance test dossiers.
