Product Introduction

APPLICATION

Building upon the conventional mineral-insulated (MI) cable with a copper conductor, MgO insulation, and seamless copper tube, this advanced iteration features an additional PVC outer sheath. This key upgrade integrates the inherent superior fire resistance of the MI structure with enhanced corrosion protection, making it ideal for low-voltage power distribution and emergency circuits where fire safety, corrosion resistance, and ease of installation are critical.

CONSTRUCTION

Conductor

Solid copper rod conductor

Insulation

High-purity magnesium oxide (MgO) powder

Inner Sheath

Seamless copper tube

 

Outer Sheath

Flame-retardant Polyvinyl chloride (PVC) or low-smoke halogen-free (LSHF) outer jacket 

Sheath Colour

Red or as your specify


Available Nominal Cross-sectional Areas

2.5-25 sqmm


CHARACTERISTICS

Rated Voltage  (Uo/U): 450/750 V
Test Voltage: 2.5 KV (5 minutes)
Max Continuous Operating Temperature: 250℃ (long-term stable operation; insulation performance unchanged)
Short-Term Overload Temperature:400℃ (maximum duration: 1 hour; no insulation degradation)
Fire Resistance Temperature:1000℃ (maintains circuit integrity for ≥ 3 hours
Temperature Rating (Fixed Installation): -50℃ to 250℃ 
Minimum Bending Radius
Single-core(OD≤10mm): 7×OD±5%    Single-core(OD>10mm): 9×OD±5%
Multi-core: 11×OD±5%  (Note: OD refers to the outer diameter of the cable)
