Specification for Suspension Wire Clamp
General Description:
- Type: Suspension Clamp (possibly a forged or cast metal design with clevis and yoke attachment points).
- Purpose: To suspend and support overhead conductors (e.g., aluminum or steel cables) on transmission or distribution lines, allowing for movement due to wind or thermal expansion while maintaining tension.
- Material:
- Body: Galvanized steel or malleable iron (indicated by the uniform gray coating and corrosion resistance).
- Hardware: Stainless steel or galvanized steel bolts, nuts, and cotter pins.
- Finish: Hot-dip galvanized to prevent corrosion, suitable for outdoor environments.
Key Components and Dimensions:
- Body:
- Shape: Elongated, cylindrical rod with a U-shaped yoke at one end and a clevis fork at the other.
- Length: Approximately 20-30 cm (estimated from image; exact measurement requires physical verification or manufacturer data).
- Diameter: Approximately 1-2 cm (estimated; precise diameter depends on load rating).
- Weight: Typically 1-3 kg (varies by size and load capacity).
- Yoke (Suspension Point):
- Design: U-shaped or saddle-like structure to cradle the conductor.
- Inner Width: Designed to accommodate conductor diameters typically ranging from 7 mm to 20 mm (e.g., for ACSR or AAC conductors).
- Attachment: Secured with a clevis pin and cotter pin (circled in red in the image).
- Purpose: Distributes the weight of the conductor and allows pivoting to reduce mechanical stress.
- Clevis Ends:
- Design: Forked ends with a bolt, nut, and cotter pin for attachment to insulators, fittings, or poles.
- Bolt Diameter: Approximately 10-12 mm (estimated; varies by load rating).
- Clevis Pin Length: Approximately 3-5 cm (estimated).
- Cotter Pin: Small (2-3 mm diameter, 2-3 cm length) to lock the clevis pin in place.
- Purpose: Connects the clamp to suspension insulators or other hardware.
- Adjustment Mechanism:
- Type: Some suspension clamps may include a tensioning feature (e.g., a turnbuckle-like adjustment), though not fully visible in the image. If present, it allows for fine-tuning of conductor tension.
- Adjustment Range: Typically 5-10 cm (if adjustable).
Performance Specifications:
- Load Capacity:
- Designed to handle vertical loads of 10-70 kN (2,250-15,700 lbs) depending on size and design (e.g., for light to medium-duty lines). An exact rating requires manufacturer data.
- Conductor Range: Suitable for conductors with diameters of 7-25 mm (e.g., ACSR, AAC, or AAAC cables).
- Insulation: If part of an insulator assembly, it may support voltages up to 11 kV, 33 kV, or higher (depending on the insulator type paired with the clamp).
- Temperature Range: Operable from -40°C to +70°C, typical for galvanized steel in outdoor settings.
Safety and Design Features:
- Cotter Pins: Used at multiple points (as circled) to prevent bolts from loosening under vibration or load.
- Pivot Design: Allows the clamp to swivel, reducing strain on the conductor during wind or thermal movement.
- Corrosion Resistance: Galvanized coating ensures longevity in harsh weather conditions.
Standards Compliance:
- Likely conforms to international standards such as:
- IEC 61284: Overhead lines - Requirements for fittings.
- ANSI C29: For insulators and related hardware (if applicable).
- BS 3288: Insulator and conductor fittings (British Standard).
- Manufacturer-specific certifications may apply (e.g., ISO 9001).
Installation and Maintenance:
- Installation: Attach to a suspension insulator or pole fitting using the clevis ends. The conductor is placed in the yoke and secured (additional straps or keepers may be used, not shown).
- Maintenance: Periodic inspection for wear, corrosion, or cotter pin integrity. Replacement of pins or bolts if damaged.
