Application scope and source hierarchy<\/h2>\n<p><b>NTSCGEWOEU<\/b> must be treated as an engineering family rather than one fixed cable. The published Feichun documents separately cover the base mining specification, reeling execution, high\/extreme PROTOLON(SMK), reinforced PROTOLON(SB), water-duty PROTOLON(ST) and the LWL branch with optical fibres. The parameters are therefore retained with their scope; a value from one branch is not automatically transferred to another.<\/p>\n<div class=\"grid\">\n  <div class=\"source\"><b>Primary Feichun mining specification<\/b><br>7 pages: 3\u00d735+2\u00d716+16 and 3\u00d795+2\u00d725+16, EPR\/NBR layers, PE, pilot, 3.6\/6 kV, physical and electrical tables, and mechanical limits.<br><a href=\"https:\/\/feichuncables.com\/blog\/wp-content\/uploads\/NTSCGEWOEU-Mining-Cable-Technical-Specification.pdf\" target=\"_blank\" rel=\"noopener\">Open the original Feichun specification<\/a><\/div>\n  <div class=\"source\"><b>Feichun reeling specification<\/b><br>5 pages: 3.6\/6 kV, complete Dmin\/Dmax, mass, tensile load, R20, capacitance, inductance, current and Isc tables, including special PE\/pilot constructions.<br><a href=\"https:\/\/feichuncables.com\/blog\/wp-content\/uploads\/NTSCGEWOEU-Reeling-Cable-Specification-Anhui-Feichun-Special-Cable-Co.-Ltd_.pdf\" target=\"_blank\" rel=\"noopener\">Open the Feichun reeling specification<\/a><\/div>\n  <div class=\"source\"><b>PROTOLON(SMK) high\/extreme<\/b><br>7 pages: 1.8\/3\u201312\/20 kV, Class FS tinned copper, \u00b125\u00b0\/m, static\/dynamic tensile load, PROTOFIRM Sandwich, temperature limits and reference matrix.<br><a href=\"https:\/\/feichuncables.com\/blog\/wp-content\/uploads\/PROTOLONSMK-NTSCGEWOEU-18_3%E2%80%9312_20-kV-_-Feichun-high_extreme-reeling-cable-1.pdf\" target=\"_blank\" rel=\"noopener\">Open the Feichun SMK specification<\/a><\/div>\n  <div class=\"source\"><b>Independent cross-check<\/b><br>Official 17-page Prysmian PDF with the same MV reeling-cable fields: conductor\/PE diameter, Dmin\/Dmax, Rfree, mass, static\/dynamic tensile load, current and short-circuit current.<br><a href=\"https:\/\/www.prysmian.com\/sites\/default\/files\/business_markets\/markets\/downloads\/datasheets\/Medium-Voltage-Round.pdf\" target=\"_blank\" rel=\"noopener\">Open the official round MV PDF<\/a><\/div>\n<\/div>\n<div class=\"warn\"><b>Data status:<\/b> the matrices are provided for preliminary engineering comparison and technical SEO navigation.

What a port or mining engineer must consider<\/h2>\n<div class=\"grid\">\n  <div class=\"box\"><b>Mechanical kinematics<\/b><br>Travel speed, acceleration, number of reversals, roller bending, churning, S-type changes and possible torsion govern service life more strongly than nominal voltage alone.<\/div>\n  <div class=\"box\"><b>Travel-path geometry<\/b><br>Drag chain, festoon trolley, ground trailing and reel operation create different combinations of radius, lateral pressure, tensile load and torsion. The same Dmax does not make the systems interchangeable.<\/div>\n  <div class=\"box\"><b>Electrical duty<\/b><br>Current capacity depends on temperature, surface installation, number of reel layers and grouping. Long runs require review of R20, capacitance, inductance, voltage drop and charging current.<\/div>\n  <div class=\"box\"><b>Certification scope<\/b><br>For ports, mines, EAEU markets and Ex zones, verify not only the cable but also the gland, termination, connector, joint, earthing, machine and site documentation.<\/div>\n<\/div>\n\n<h2>3.
