Distinguish metallic tape shield from concentric-neutral construction for documented medium-voltage reels.
Checkable specification fields
These are examples from the named references, not assertions about a reel you have not shown us. Match the actual jacket, tag and part number before using a product claim.
| Field | Documented example / boundary | Source |
|---|---|---|
| Documented scope | Seattle City Light 6015.00 covers certain single- and three-conductor medium-voltage cables in a 5–46 kV procurement scope. | [1] |
| Metallic tape shield | That standard references ANSI/ICEA S-97-682 for the specified tape-shield construction. | [1] |
| Flat strap/neutral | It references ANSI/ICEA S-94-649 for specified flat-strap metallic shields or concentric-neutral constructions. | [1] |
| Manufacturer variants | Prysmian describes both flat-strap copper concentric neutrals and a separate overlapped copper-tape LC SHIELD example. | [2] |
Classify the metallic layer correctly
A semiconducting conductor or insulation shield is not the same as the metallic shield or concentric-neutral conductors. Record the exact layer construction from a manufacturer drawing, legible legend and safe disconnected end image. A quoted voltage class must also come from the offered reel, not a generic 5–46 kV brochure range.
- Use “tape metallic shield,” “flat-strap shield” or “concentric neutral” only when verified.
- Record conductor metal, insulation, jacket and voltage class separately.
- Identify the reel ID, maker, length marks and any linked certified production report.
Do not equate provenance with present fitness
Sequential marks and a historical certified test report help trace a production lot; they do not show how that reel was stored or whether water entered an open end. Capture physical condition and missing records separately, and leave suitability for future service to a qualified buyer.
- Request both cable-end photos and original reel/shipping documentation.
- Do not suggest an installation, splicing or energized testing procedure.
Source notes and scope
The linked references support the specific examples above. Product designs and standards can change; seller-supplied markings, measured length and current condition require separate verification. Nothing here states that this buyer stocks, tests, guarantees or accepts a particular cable, or offers installation advice.
