GG Extreme temperature adaptability Silicone Rubber Cable

Excellent Chemical Resistance:
- Resistant to oil, solvents, acids, and alkalis (except strong acids/bases)  
- Resistant to ozone and UV radiation (withstands direct outdoor exposure for over 10 years)  
Mechanical and Safety Characteristics:
- High flexibility: dynamic bending lifespan far exceeds that of ordinary rubber cables  
- Flame-retardant and self-extinguishing: self-extinguishes within 2 seconds after flame removal (VW-1)  
- Low smoke and non-toxic: smoke density during combustion <150 (IEC 61034)  
Electrical Reliability:  
- Insulation resistance remains stable at high temperatures  
Application Scope:  
Used in harsh industrial environments, specialized equipment, and high-end facilities where extreme temperatures, frequent movement, severe chemical corrosion, or high fire safety requirements are present.

Core Number Range:1-core (single-core power cable) to 50-cores (control cable)  
Cross-sectional Area Range: 
- Low-voltage power type: 0.5 mm² to 400 mm² (large cross-sections for high current)  
- Control/signal type: 0.2 mm² to 6 mm² (multi-core stranded, with overall shielding)  
Conductor: Class 5 or Class 6 multi-strand tinned copper (corrosion-resistant) or bare copper; nickel-clad copper (ultra-high temperature resistant) optional  
Insulation: Silicone rubber, thickness customized according to voltage rating and cross-section  
Sheath Options:
