高純度導体：電力伝送のための純粋なチャネル
In the invisible veins of the electrical system, wires and cables are the lifeline of modern civilization, and their safety performance is directly related to life, property and system stability. As an industry benchmark, the safety barrier built by Rifeng Cable is not accidental, but is derived from the precise coordination of six core characteristics, weaving an invisible but tough safety net for thousands of households and key facilities.
Conductors are the cornerstone of cable transmission.
2.Advanced insulation barrier: a reliable “isolation wall” for current
strictly selects 99.99% oxygen-free copper (OFC) or high-conductivity aluminum alloy as the core material of the conductor. Its ultra-low resistance characteristics (in line with the highest level standard of IEC 60228) significantly reduce energy loss and abnormal heating in current transmission, and eliminate the risk of insulation aging and even fire caused by conductor overheating from the source. High-purity conductors are like unobstructed highways, ensuring stable and efficient flow of current.

is the global benchmark for measuring the conductive performance of conductor materials.
3.Excellent flame retardant performance: a powerful “brake” for fire spread
The insulation layer is the direct line of defense against leakage and short circuit. Rifeng Cable goes beyond ordinary PVC and widely uses materials such as cross-linked polyethylene (XLPE). Through a special cross-linking process, XLPE has a heat resistance level (usually up to 90°C-125°C), mechanical strength and chemical corrosion resistance far superior to traditional materials. Even under high temperature, heavy pressure or harsh environment, its molecular structure remains stable, effectively isolating the conductor and ensuring that the current flows safely only within the set path. This layer of “technological armor” greatly extends the life of the cable and reduces the failure rate.
Industry insights: The National Electrical Code (NEC) of the United States has strict regulations on the temperature level and application environment of different insulation materials, such as Article 310.15. Fire is one of the biggest threats to electrical safety. Rifeng Cable’s flame retardant series products (such as models that meet GB/T 19666 and IEC 60332 standards) adopt special formulas and structural designs. Its insulation and sheath materials can quickly self-extinguish in flames, forming a solid carbonized layer to isolate oxygen, and greatly inhibit the release of toxic smoke and corrosive gases (in line with IEC 60754 low halogen/halogen-free requirements). This “active defense” mechanism buys precious time for personnel escape and fire rescue, and significantly reduces fire losses.Safety standards: Internationally used cable combustion test standards, such as IEC 60332 (vertical flame spread), IEC 61034 (smoke density), and IEC 60754 (gas acidity) are the golden keys to measure flame retardant safety.

In the modern complex electromagnetic environment, interference is like “electronic noise” pollution. Rifeng Cable is equipped with copper wire braiding, aluminum-plastic composite tape and other multi-layer shielding structures for key signal transmission lines (such as data and control cables). These designs are like precise Faraday cages, which efficiently absorb or reflect external electromagnetic interference (EMI/RFI), while preventing internal signal leakage, ensuring signal purity and transmission reliability for high-precision systems such as medical equipment monitoring and industrial automation control, and avoiding safety accidents caused by misoperation.
Technical basis: Electromagnetic compatibility (EMC) is the basis for the safe operation of electronic systems. Relevant standards such as IEC 60092-350 have detailed requirements for the shielding effectiveness of marine cables.
Safety is not a slogan, but a verifiable system. Rifeng Cable has established an ISO 9001 quality management system that covers the entire chain from raw materials entering the factory, production process to finished products leaving the factory. Its products not only meet the national compulsory certification (CCC), but also actively obtain international authoritative certifications such as UL (US), CE (Europe), KEMA (Netherlands), etc. These certifications are like third-party “safety audits”. Through rigorous tests by independent laboratories (such as long-term aging and short-circuit tolerance), they ensure that the performance parameters of each meter of cable are stable and reliable, and comply with the world’s most stringent safety regulations.
