Bolted Strain Clamp

The Bolted Strain Clamp is used to secure conductors at overhead transmission and distribution line terminals, angle poles, and strain poles.
Typical compatible conductors include aluminum stranded conductor, aluminum conductor steel-reinforced, and certain overhead bare conductors.
Model selection should start from the actual conductor cross-section and line arrangement, because mechanical performance is confirmed by clamp model, conductor specification, and project requirement.

Multi-Bolt Clamping Structure

The body is aluminum alloy, paired with galvanized steel bolts or U-bolts.

A multi-bolt compression layout distributes clamping force over a longer conductor contact area for terminal, angle, and strain positions.

Groove diameter, number of bolts, body length, and associated connection dimensions can vary with the conductor specification.

Outdoor Material Pairing

The aluminum-alloy body is suited to matching aluminum conductor applications listed in the source material.

Steel fasteners and related steel components normally use hot-dip galvanized surface treatment for outdoor rain and ordinary atmospheric exposure.

Buyers should identify both conductor material and the connected tower hardware when confirming a replacement clamp.

Drawing-Based Dimensional Adjustment

Production can follow conductor cross-section, clamp assembly drawings, or an existing product sample.

Project-specific adjustment can cover groove diameter, bolt quantity, body length, and connection dimensions.

This is useful for line renovation where the existing conductor remains in service but the strain hardware needs replacement.

Inspection and Packing by Assembly

Quality control covers raw materials, production, and finished-product release. Finished clamps receive 100% inspection before packing, and third-party inspection is supported.

Technical documents and inspection support can be provided for confirmed project specifications.

Packing groups the clamp body, bolts, and associated connection parts according to order configuration. Standard production is generally 30 days and customized production 45 days, with progress photos or video available.

For a Bolted Strain Clamp inquiry, send conductor type, cross-section, assembly drawing, and required connection dimensions.
