Multi-Core Fire-Resistant Instrumentation Cable CU/MGT/XLPE/OS/FR/LSZH/GSWA/LSZH 2×2.5mm²
Premium-Grade Circuit Integrity for Mission-Critical Applications
Engineered for Extreme Reliability
Our 2×2.5mm² fire-resistant instrumentation cable sets the industry standard for secure power and signal transmission in high-risk environments. Featuring twin 2.5mm² tinned copper conductors with military-grade protection systems, this cable delivers uninterrupted performance even under direct fire exposure.
Critical Safety Architecture
◆ Fire Survival Core - Maintains circuit integrity for 180+ minutes at 950°C (IEC 60331 compliant)
◆ Toxic-Free Protection - Dual-layer LSZH sheathing prevents hazardous gas emission (IEC 60754-1)
◆ Armored Defense - Heavy-duty GSWA provides 360° mechanical protection (2000N crush resistance)
◆ EMI Fortification - MGT+OS shielding combination achieves >90% interference rejection
