Product Overview
The CJPJP80/SC is a specialized marine power cable designed for applications requiring a combination of enhanced thermal/mechanical performance from the inner sheath and flexible, corrosion-resistant armor. Its key feature is the use of a Cross-linked Polyolefin (SHF2) inner sheath, which offers superior temperature and deformation resistance compared to standard thermoplastic sheaths. Combined with XLPE insulation, a collective screen, and a tinned copper wire braid armor, this cable provides a reliable and durable solution for dynamic or fixed installations where both electrical integrity and mechanical flexibility are critical.
Key Features & Benefits
-
Enhanced Inner Sheath: Features a Cross-linked Polyolefin (SHF2) inner sheath, providing improved resistance to heat deformation, cracking, and mechanical stress over standard materials, ensuring long-term integrity.
-
Flexible & Corrosion-Resistant Armor: Braided armor made of tinned copper wires offers excellent flexibility, ease of termination, and inherent corrosion resistance, making it ideal for marine atmospheres.
-
Superior Fire Safety: All polymeric materials are Halogen-Free and Low-Smoke (LSZH), minimizing toxic gas emission and smoke density to enhance safety during fire incidents.
-
Stable Electrical Core: XLPE insulation ensures high dielectric strength and thermal stability for continuous operation at 90°C.
-
Effective EMI Shielding: The collective copper screen protects against electromagnetic interference, safeguarding signal integrity for power and sensitive control circuits.
