Designed to support ultra-high-speed data transmission, electromagnetic immunity, and long-distance stable connectivity, CAT7 cables from HUALUE are engineered with industry-leading shielding architecture and precision manufacturing. This white paper details the structure, production process, testing methodologies, key performance metrics, application-specific advantages, and international standards compliance that position HUALUE CAT7 cables as the preferred choice in enterprise, data center, and high-end residential environments.

1. Advanced Structure Design

HUALUE CAT7 cables adopt a high-performance S/FTP (Shielded Foiled Twisted Pair) structure that exceeds Category 6A requirements:

Layer	Material	Function
Conductor	23 AWG solid oxygen-free copper	Low resistance, high signal integrity
Insulation	High-density polyethylene (HDPE)	High dielectric performance
Twisted Pair	Precision pair twisting (15–35 mm)	Crosstalk suppression
Individual Shielding	Aluminum foil (per pair)	Near-end and far-end interference reduction
Overall Shielding	Tinned copper braid (>85% coverage)	EMI/RFI shielding
Outer Jacket	LSZH, PVC or PE	Flame resistance, UV resistance (outdoor)

HUALUE implements automated twisting and foil-wrapping machines for consistent mechanical and electrical properties across all product batches.

2. Precision Manufacturing Process

HUALUE CAT7 cables are manufactured under stringent process control systems:

Copper drawing & annealing
Core insulation extrusion (HDPE)
Pair twisting (controlled pitch)
Foil wrapping for each pair
Cable forming with total braid shielding
Jacket extrusion (depending on use case: indoor/outdoor/LSZH)
Meter marking, coiling, packaging
100% Electrical testing and visual inspection

Key Process Tolerances:

Twisting pitch precision: ±1 mm
Shield overlap: >100%
Insulation eccentricity: <10%
Conductor resistance: ≤16.5 Ω/100 m
