NF M87-202 Standard Overview Descripción General de la Norma NF M87-202 NF M87-202標準概述
NF M87-202 is the French National Standard (Norme Française) that defines the requirements for both armoured and unarmoured instrumentation cables specifically designed for the petroleum and petrochemical industry. These specialized cables serve the critical function of connecting electrical circuits and providing communication services in process plants where reliability and safety are paramount.
The standard covers cables designed for safe extra-low voltage (SELV) applications, suitable for the transmission of both AC and DC analogue signals. With a voltage rating of 300/500V, these cables are engineered for environments where resistance to aliphatic and aromatic hydrocarbons is essential. The cables are available in cores, pairs, and multi-pair configurations to accommodate various instrumentation and control system requirements.
All NF M87-202 cables feature comprehensive screening using Al/PET (Aluminium/Polyester) tapes to ensure signal integrity and protection against electromagnetic interference—a critical requirement in industrial process control environments. The standard encompasses four main cable types: EGFA, EGSF, EIFA, and EISF, each with distinct construction characteristics to meet different installation requirements.
NF M87-202 es la Norma Nacional Francesa (Norme Française) que define los requisitos para cables de instrumentación armados y no armados, diseñados específicamente para la industria del petróleo y petroquímica. Estos cables especializados cumplen la función crítica de conectar circuitos eléctricos y proporcionar servicios de comunicación en plantas de proceso donde la confiabilidad y la seguridad son primordiales.
La norma cubre cables diseñados para aplicaciones de tensión extra baja de seguridad (SELV), adecuados para la transmisión de señales analógicas de CA y CC. Con una clasificación de voltaje de 300/500V, estos cables están diseñados para entornos donde la resistencia a hidrocarburos alifáticos y aromáticos es esencial. Los cables están disponibles en configuraciones de núcleos, pares y multi-pares para adaptarse a diversos requisitos de instrumentación y sistemas de control.
Todos los cables NF M87-202 cuentan con un apantallamiento integral utilizando cintas de Al/PET (Aluminio/Poliéster) para garantizar la integridad de la señal y la protección contra interferencias electromagnéticas, un requisito crítico en entornos de control de procesos industriales. La norma abarca cuatro tipos principales de cables: EGFA, EGSF, EIFA y EISF, cada uno con características de construcción distintas para satisfacer diferentes requisitos de instalación.
NF M87-202是法國國家標準（Norme Française），定義了專門為石油和石化工業設計的鎧裝和非鎧裝儀表電纜的要求。這些專用電纜在過程工廠中執行連接電氣電路和提供通信服務的關鍵功能，在這些場所，可靠性和安全性至關重要。
該標準涵蓋為安全特低電壓（SELV）應用設計的電纜，適用於交流和直流模擬信號的傳輸。這些電纜的額定電壓為300/500V，專為需要耐脂肪族和芳香族碳氫化合物的環境而設計。電纜可提供芯線、對線和多對配置，以適應各種儀表和控制系統的要求。
所有NF M87-202電纜都採用Al/PET（鋁/聚酯）帶進行全面屏蔽，以確保信號完整性並防止電磁干擾——這是工業過程控制環境中的關鍵要求。該標準涵蓋四種主要電纜類型：EGFA、EGSF、EIFA和EISF，每種都具有不同的結構特性，以滿足不同的安裝要求。
