Silicone Rubber Shielded Cable – High Flex + High Temperature Rating
Ultra-flexible silicone rubber shielded cable rated -60°C to +200°C (peak 250°C). Multi-strand tinned copper conductors + double shielding (aluminum foil + high-coverage copper braid) deliver superior EMI suppression in VFD/servo environments. Outstanding tear resistance, oil/chemical tolerance, and millions of bend cycles. Customize core count (2–60), cross-sections, jacket colors, sequential printing, aramid strength members. Ideal for industrial robots, metallurgy hot zones, glass kilns, automotive bake ovens, aerospace test stands, and dynamic drag-chain systems. CE/RoHS/REACH compliant, exported to 100+ countries with fast 15–30 day lead times from Shanghai Rousheng – proven in extreme heat & motion since 2010.
Built for Heat + Heavy Motion – Real-World Reliability
Industrial environments rarely offer gentle conditions. VFD-driven motors generate EMI spikes, robotic arms demand millions of flex cycles, and furnace-adjacent wiring sees sustained 200°C heat. Ordinary cables crack, lose shielding effectiveness, or fail prematurely. Our silicone rubber shielded cable is purpose-built to survive these combined stresses.
Case Study: Since 2010, Shanghai Rousheng has supplied this construction to European robotics integrators, Asian metallurgical plants, and North American aerospace test facilities. In one documented case, a German automotive Tier-1 supplier replaced PTFE-based wiring with our double-shielded silicone design in a 180°C paint-bake robot cell—downtime dropped 87% over 18 months due to zero flex-related failures (internal field report, 2024).
Standout Technical Advantages
-
Extreme Thermal Range: Continuous 200°C rating with short peaks to 250–280°C (compound-dependent).
-
Superior EMI Protection: Double shielding (aluminum/polyester foil + ≥85% tinned copper braid) providing >60 dB attenuation in 30–1000 MHz range.
-
High Flexibility: Fine multi-strand tinned copper (Class 5 or 6) combined with high-elasticity silicone allows for a bend radius as low as 5× outer diameter.
-
Chemical Resilience: Exceptional resistance to oil, solvents, ozone, and UV compared to standard PVC/XLPE.
-
Mechanical Strength: Optional aramid (Kevlar®) central strength member for tensile loads up to 2,500 N.

Frequently Asked Questions
What is the actual long-term temperature endurance?
200°C continuous in air; lab aging tests (IEC 60216) show >20,000 hours at 200°C with <30% property loss.
How much EMI protection does the double shielding provide?
Typically >60 dB attenuation (30–1000 MHz) in our anechoic chamber tests—effective against VFD harmonics up to 16 kHz.
What is the smallest bend radius in dynamic use?
5 × outer diameter for most models; we validate via 5-million-cycle drag-chain test at room & elevated temperature.
Is the cable oil-resistant?
Standard silicone offers good resistance; we offer an enhanced oil-resistant compound for severe exposure (IRM 902/903 fluids).
What are the order and lead time specifics?
Minimum order is 100 meters for most constructions. Lead times range from 7–12 days for near-stock specs to 15–30 days for full custom orders.
