Concentric Neutral Construction
Neutral or earth conductors are arranged concentrically around the insulated phase core for service cable routes.
100% / 133% Insulation Concentric Cable
Concentric neutral cable for service entrance and utility distribution.
100% / 133% Insulation Concentric Cable is used for low-voltage service and distribution routes where concentric neutral design, anti-tamper performance and utility standard selection are important.
Product Overview
100% / 133% Insulation Concentric Cable should be selected according to the actual project route, not by product name alone. Before quotation, review voltage grade, concentric neutral coverage, conductor material, flat or round profile and utility code route. Datasheet wording, compliance documents and final supply notes should stay aligned with the selected standard and installation conditions.
Applications
- utility service entrance and distribution routes
- anti-tamper or revenue-protection cable projects
- overhead, duct or direct-burial routes as specified
- regional utility tenders requiring concentric cable construction
Construction
Phase conductor with insulation and concentric neutral or earth conductor arrangement. Copper or aluminum conductor route, insulation percentage, flat/round profile and sheath material should follow utility and project requirements.
Marking on Cable
FARWALK CABLE – 100% / 133% Insulation Concentric Cable – [standard] – [voltage] – [size] – [year] – [meter mark]
Cable Identification
- Phase, neutral and earth arrangement should be identified according to the selected concentric cable design.
- Sheath color and printed marking can follow utility or project requirement.
Standards
- IEC 60502-1
- UL 854
- ASTM B800 / B801
- project utility requirements
Main Features
Anti-Tamper Utility Use
Designed for LV service entrance, distribution and metering routes where anti-theft performance is required.
Standard and Material Options
For 100% / 133% Insulation Concentric Cable, copper, aluminum and 8000-series alloy constructions can be reviewed according to IEC, UL, ASTM or utility routes.
Product Selection Guide
Voltage Grade
Separate LV service cable from MV concentric neutral routes; insulation, screen and test requirements are different.
Neutral Coverage
Confirm split, full neutral, concentric earth or CNE arrangement according to utility service rules.
Conductor Material
Choose copper, aluminum or 8000-series alloy after comparing cost, ampacity, termination and local acceptance.
Profile and Standard
Select flat or round profile and match IEC, UL, ASTM, BS or utility standards before quotation.
