Engineering documentation

Spec matrix, IEC type-tests, MV screen design.

Nine cable families, 80+ rows of conductor-class-aware spec data, four MV voltage tiers (6/10 → 26/35 kV) with IEC 60502-2 screen design, and eight type-test reports from CESI / DNV KEMA / TÜV Rheinland. Each row plugs straight into a single-line diagram review.

The lab, standard, and scope for each report below are fixed; the report number, issue date, and signed PDF are released on issuance, under NDA, at first qualified RFQ. The verify-portal links below open each lab's public lookup so buyers can cross-reference the issued number.

MV scope today. Current MV bid scope: 6/10 kV — IEC 60502-2 type-test on file, Class 2 and Class 5 conductors, 12-bracket spec matrix below. YJV22 12/20 kV rows are referenced against IEC 60502-2 standard construction and are in coordinated re-test for per-voltage-class confirmation; useful for engineering preview, but anchor 12/20 kV tender prequalification on the confirmed per-voltage-class scope (release timeline in /about).

Trust posture

Engineering claims stay datasheet-gated.

Construction stack

Outer sheath, insulation, conductor, shield or armor — buyer-readable layers.

Order package

Coils, 305 m boxes, drums, end caps, and handling cues.

Route risk

Buried runs, tunnels, trays, control cabinets, risers tied to family selection.

Document gate

Certificate wording, test reports, payee, model coverage stay verified before order.
