UL 4511 High-Temperature Silicone Rubber Cable | Halogen-Free, Shielded Industrial Cable

Silicone Rubber Insulated Cables23
Description

UL 4511 Wire silicone rubber cable

Product Overview

The UL 4511 Silicone Rubber Cable is a premium halogen-free solution engineered for extreme environments where standard cables fail. Featuring high-temperature silicone rubber insulation and specialized jacketing, it delivers exceptional resistance to heat, saltwater corrosion, UV radiation, mechanical stress, and electromagnetic interference (EMI). UL Listed for guaranteed compliance with rigorous safety standards.

Key Features & Benefits:

  • Extreme Temperature Resilience: Continuous operation at +180°C (+200°C UL/CSA), short-term up to +250°C. Reliable performance from -40°C to +180°C (static) and -25°C to +180°C (flexing).

  • Halogen-Free Safety: Zero toxic/corrosive gas emissions during combustion.

  • Environmental Resistance: Superior performance in saltwater, high-humidity, UV-exposed, and chemical environments.

  • Mechanical Durability: Resists abrasion, cutting, tearing, and industrial abuse.

  • EMI/RFI Protection: Integrated tinned copper braid shield ensures signal integrity.

  • Flame Performance: Self-extinguishing with low smoke emission.

  • Radiation Resistant: Withstands doses up to 2 × 10⁷ cJ/kg.

Primary Applications:

Critical environments requiring robust performance:

  • Heavy Industry: Foundries, steel mills, glass plants (furnaces, kilns, casting lines)

  • High-Temperature Processes: Industrial ovens, baking equipment, burners, heaters

  • Marine Settings: Offshore platforms, coastal facilities, shipboard systems

  • EMI-Sensitive Areas: Control circuits, instrumentation, power distribution

  • Harsh Environments: UV-exposed locations, radiation zones, chemical exposure

Engineering Selection Notes:

  1. Shielding: Essential for EMI-prone applications or signal-critical systems

  2. Temperature: Verify continuous operating temperature matches process requirements

  3. Bending Radius: Strictly maintain 5×OD (fixed) / 10×OD (flexing) during installation

  4. Chemical Exposure: Validate compatibility with site-specific chemicals

  5. Certification: Always reference actual UL file (EXXXXX) for project specifications.
