Product Overview
The CHEPJP95/NC is a premium-grade, halogen-free, low-smoke, fire-resistant screened marine communication cable engineered for the most critical data and signal transmission systems. Designed to maintain circuit integrity during a fire, it combines a mica glass tape and EPR fire-resistant insulation, a fully cross-linked polyolefin (SHF2) dual-sheath system, individual pair/overall screening, and galvanized steel wire armor. This comprehensive construction ensures ultimate safety, signal clarity, and physical protection for vital telecommunications, instrumentation, and control networks in demanding marine and industrial environments.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The core insulation system (mica glass tape + EPR) is designed to maintain circuit integrity and ensure continued signal transmission for a specified period under direct flame, which is critical for emergency communications and safety systems.
-
Complete Halogen-Free Safety Package: Integrates fire resistance with halogen-free materials (IEC 60754) and low smoke emission (IEC 61034), minimizing corrosive gas and dense smoke production during a fire to protect personnel and equipment.
-
Superior Screening & EMI Protection: Features individual pair/overall screening (tinned copper braid or Alu/Polyester tape) to protect sensitive communication signals from electromagnetic interference (EMI) and crosstalk, ensuring high signal integrity.
-
Maximum Physical & Environmental Protection: The galvanized steel wire braid armor provides supreme mechanical strength. The full cross-linked polyolefin (SHF2) outer sheath offers excellent thermal endurance and resistance to abrasion, oils, and chemicals.
-
Enhanced High-Temperature Sheath System: Both inner and outer sheaths are made of cross-linked polyolefin (SHF2), providing superior thermal stability in elevated ambient temperature environments.
