Wear-resistant Liquid Silicone Cable Fixing Clamp Wire Positioning Protective Fastener

Core design features include an integrated serrated inner gripping surface that prevents cable slippage under vibration, a rounded edge profile that eliminates insulation abrasion, and a universal mounting hole compatible with M3 to M6 screws, rivets, or adhesive backings for versatile installation. Unlike rigid plastic clamps that crack under low temperatures or deform under sustained heat, our LSR fixing clamps maintain consistent clamping force across a -60°C to 220°C operating range, while their inherent UV and ozone resistance makes them suitable for both indoor and outdoor deployments. The product is available in 8 standard sizes to accommodate cable diameters from 2mm to 30mm, with custom molding options for unique cable profiles, color coding, or branding requirements.

Technical Specifications

Material Properties

All LSR cable fixing clamps are manufactured from high-purity platinum-cured liquid silicone rubber, with optional material grades tailored to specific application requirements:

Physical Performance

Process Parameters

The clamps are produced via high-precision LSR injection molding with the following standard process conditions, adjustable for custom formulations:

Product Advantages

1. Superior Long-Term Wear and Fatigue Resistance

Unlike rigid PA66 plastic clamps that become brittle after 1~2 years of outdoor exposure, or EPDM rubber clamps that lose clamping force after 500+ temperature cycles, our LSR clamps retain 90% of their original physical properties after 10 years of continuous use. The serrated inner grip surface is engineered to distribute clamping force evenly across cable insulation, reducing localized wear by 75% compared to smooth plastic clamps, even under constant vibration from industrial machinery or automotive powertrains.

1. Extreme Environmental Adaptability

The clamp maintains full functionality across extreme temperature fluctuations, making it suitable for deployments in polar cold chain equipment, desert solar installations, and high-temperature automotive engine bays. Its inherent UV and ozone resistance eliminates the need for additional protective coatings, while its waterproof and dustproof properties prevent corrosion of underlying cable connections in outdoor or high-humidity environments such as marine equipment or underground mining wiring systems.

1. Non-Damaging Cable Protection

The low-modulus, flexible LSR material and rounded, burr-free edge profile eliminate the risk of cutting or abrading cable insulation, even when cables are subject to frequent movement or thermal expansion and contraction. Unlike metal clamps that require separate rubber padding to avoid insulation damage, our all-in-one LSR design reduces installation time and material costs while providing consistent, long-term insulation protection for high-voltage, signal, and fiber optic cables.

1. Versatile, Low-Cost Installation

The standard mounting hole is compatible with all common M3 to M6 fasteners, and optional 3M VHB adhesive backing is available for tool-free installation on smooth surfaces. The clamp’s flexible opening allows for one-handed cable insertion, reducing installation time by 40% compared to two-piece plastic clamps. For high-volume deployments, custom color coding can be molded directly into the clamp to simplify cable identification and maintenance.

Applications

• Automotive and New Energy Vehicles (NEVs): Used to fix high-voltage power cables, battery management system (BMS) wiring harnesses, and sensor cables in electric vehicle (EV) powertrains, chassis, and interior compartments. The UL94 V-0 flammability rating and -40°C to 180°C operating range of the automotive-grade clamps meet ISO 16750 road vehicle environmental standards.
• Industrial Automation: Ideal for securing control wiring, sensor cables, and power cords on robotic arms, conveyor systems, and CNC machine tools that are subject to constant vibration, lubricant exposure, and temperature fluctuations. The oil-resistant LSR formulation retains clamping force after prolonged contact with hydraulic fluids and industrial lubricants.
• Telecommunications and Data Centers: Used to organize and protect fiber optic cables, Cat6/Cat7 Ethernet cables, and power distribution cables in server racks and outdoor 5G base stations. The low dielectric constant of LSR prevents signal interference, while the non-abrasive profile eliminates the risk of fiber microcracks that cause signal loss.
• Renewable Energy: Suitable for fixing DC power cables in solar panel arrays and wind turbine nacelles, where UV resistance, wide temperature tolerance, and long service life are critical for 25-year system warranties.
• Medical and Healthcare Equipment: The medical-grade clamp is used to secure power and data cables in MRI machines, patient monitors, and surgical equipment, meeting ISO 10993 biocompatibility requirements for non-skin contact applications, and withstanding repeated autoclave sterilization cycles.
• Marine and Aerospace: The saltwater-resistant LSR grade is used for cable management in shipboard wiring systems and aerospace cabin interiors, with compliance to relevant marine and aerospace material standards available upon request.

Selection Guide

Hardness Selection

• 40 Shore A: Recommended for fragile cables (fiber optic, small-gauge signal wires) and applications requiring minimal insulation stress, with maximum flexibility for frequent cable repositioning.
• 50~60 Shore A: The standard general-purpose option, ideal for most power cables, automotive wiring harnesses, and industrial automation applications, balancing grip force and flexibility.
• 70 Shore A: Designed for heavy-duty high-voltage cables, large-diameter wiring, and high-vibration environments where maximum holding force is required.

Size Specifications

Select the clamp inner diameter 0.5~1mm smaller than the outer diameter of the target cable to ensure optimal holding force without over-compressing the cable insulation. Standard available inner diameters include: 3mm, 5mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 30mm. Custom sizes and non-circular inner profiles for flat or ribbon cables are available for minimum order quantities (MOQs) of 5000 units.

Material Grade

• Standard Industrial Grade: Cost-effective option for indoor general industrial applications, RoHS and REACH compliant.
• Automotive Grade: Enhanced temperature and oil resistance, UL94 V-0 rated, meets IATF 16949 manufacturing requirements.
• Food/Medical Grade: Platinum-cured, non-toxic, ISO 10993 biocompatible, suitable for food processing equipment and medical device applications.
• High-Temperature Grade: Suitable for continuous operation up to 300°C, designed for aerospace and industrial furnace applications.

Quality Assurance

All LSR cable fixing clamps are manufactured in our ISO 9001 and IATF 16949 certified facilities, with a multi-stage quality control process that includes incoming raw material purity testing, in-process dimensional inspection (100% inspection for critical features such as inner diameter and mounting hole size), and batch performance testing of tensile strength, clamping force, and temperature resistance before shipment.

Standard certifications for all products include RoHS 2.0, REACH, and CE compliance. Automotive-grade clamps come with IATF 16949 process certification and UL94 V-0 flammability test reports, while medical-grade products are supplied with ISO 10993 biocompatibility test reports upon request. We offer a 5-year functional warranty for all standard clamps against cracking, loss of clamping force, or material degradation under normal operating conditions, with custom warranty terms available for high-volume OEM customers. All products are traceable via batch numbers printed on each clamp, enabling full supply chain transparency for quality management purposes.
