PRODUCT PARAMETERS

  • Vibration Resistance Performance: NFE 25-511 conical serrated washers utilize a spring-effect geometry combined with radial teeth to prevent bolt loosening under high dynamic loads.
  • Enhanced Electrical Bonding: The specialized serrated profile is designed to penetrate surface oxidation and coatings, establishing a reliable metal-to-metal connection for electrical earthing.
  • Yellow Zinc Passivation: Premium yellow zinc plating (iridescent passivation) provides a thicker protective layer and superior corrosion resistance compared to standard clear zinc.
  • High-Elasticity Foundation: Manufactured from precision-hardened spring steel to maintain constant axial tension and compensate for joint relaxation or thermal expansion.
  • Industrial Standard Compliance: Fully certified to French NFE 25-511 specifications, making it the preferred choice for automotive, railway, and electrical infrastructure.

Product Features & Engineering Logic

Key AreaFeatureAdvantageBenefit
Operational AccessDouble-sided pull design; cable head can be threaded out.Enables quick connection and release at any point in the cable run, supporting mid-span installation.Maximized Efficiency: Significantly reduces labor time and resource consumption.
Structural IntegrityCompression connections are formed using Swedish TALURIT and Taiwanese WIROP hydraulic presses.Delivers a smooth finish and verified high tensile load capacity.Safety & Compliance: Ensures the connection exceeds safety margins and will not fail under rated load, protecting both infrastructure and personnel.
Material DurabilityChoice of HDG, SS 304, or SS 316 wire rope.Allows selection of optimal wear and corrosion resistance for specific environments (e.g., marine or high-humidity).Extended Lifespan: Ensures long-term reliability and reduced procurement frequency.
Cable ProtectionHighly flexible, closely woven mesh that tightens under tension but releases when pushed in the opposite direction.Allows the cable to easily pass bends without injury.Cost Mitigation: Prevents jacket damage and cable insulation compromise, avoiding expensive cable replacement and project delays.

FAQs

Q1: What is the key functional difference from standard single-eye grips?

The MGS features a double-sided pull design, with the core value being its support for mid-span cable installation, connection, or detachment. Standard single-eye grips are limited to end-to-end pulling.
