The preformed guy grip dead end is a key accessory used to fix the conductor or ground wire terminal in the power transmission system. It is specially designed for scenes such as high-voltage transmission towers, substations, and communication base stations.
High strength and corrosion resistance
Made of 6063-T6 aluminum alloy or stainless steel, with hot-dip galvanizing or epoxy coating technology, the tensile strength is ≥50kN, and the salt spray corrosion resistance is more than 2000 hours, suitable for harsh environments such as coastal areas and high humidity.
Pre-twisted innovative design
The spiral preformed structure can be installed manually without tools, fits tightly to the wire, avoids damage to the wire caused by traditional crimping process, and reduces safety costs and time.
Wide adaptability
Supports wire diameter range of 8mm-40mm, can be customized to match different specifications (such as ACSR, AAAC, OPGW and other wire types), and provides multi-strand or single-strand wire clamp options.
Excellent anti-fatigue performance
The number of cycles under dynamic load test is ≥ 1,000,000 times, which can effectively cope with periodic external force impacts such as wind vibration, ice and snow, and extend the life of the power transmission system.
Handan Jinmai adopts a full-process digital production system to ensure the quality and consistency of pre-twisted suspension clamps:
Material selection: High-purity alloy raw materials are screened through spectral analysis to ensure that the mechanical properties of the materials meet the standards.
Precision molding: The spiral structure is processed by CNC winding equipment, and the tolerance is controlled within ±0.2mm.
Surface treatment: Automated hot-dip galvanizing line or spraying line treatment, thickness ≥ 80 μm, achieving C5 level corrosion protection (ISO12944 standard).
Rigorous testing: Tensile testing, salt spray testing and 3D dimension scanning are performed on each piece to ensure 100% compliance with international standards such as IEC 61284 and ASTM F855.
Applicable wire diameter: 8mm-40mm (supports non-standard customization)
Material: 6063-T6 aluminum alloy/304 stainless steel
Breaking tensile force: ≥50kN (standard type, can be customized up to 200kN)
Operating temperature: -40℃ to +80℃
Protection level: IP68 (waterproof and dustproof)
Surface treatment: hot-dip galvanizing/epoxy spraying/Dacromet (optional)
Weight range: 0.5kg-8.5kg (depending on specifications)
Certification standards: IEC 61284, ASTM F855, GB/T2314
