Double Arming Plate/Yoke Plate

Double Arming Plate/Yoke Plate (JY-00400-01/JY-00400-02) is a hot-dip galvanized steel string hardware fitting for high-voltage transmission lines, designed to couple electrical clevis, socket tongue, and insulators. It comes in two specs: JY-00400-01 (4×1 1/2" steel size, 24" length, 13/16" hole, 13/16×3 1/2" slot, 563.00kg/100pcs, 5pcs/bundle) and JY-00400-02 (4×1 1/4" steel size, 24" length, 11/16" hole, 11/16×3" slot, 210.00kg/100pcs, 10pcs/bundle), forged for high structural strength in power transmission systems.

This Yoke Plate features forged steel construction and dual specs for versatile power transmission infrastructure use.

• Precision coupling: Creates secure connections between clevis, socket tongue, and insulators in transmission line string hardware.

• Dual-spec design: Two size variants fit different insulator and hardware models for versatile application.

• Corrosion resistance: Hot-dip galvanization (ASTM A153/ISO 1461) resists outdoor and industrial corrosion.

• High load capacity: Forged steel construction withstands the mechanical stress of overhead high-voltage lines.

• Standardized packaging: 5/10 pieces per bundle simplifies storage and bulk shipping.

• High-voltage power transmission lines (connecting string hardware on transmission towers).

• Substation infrastructure (coupling clevis and insulators in substation string systems).

• Medium-voltage power distribution lines with heavy-duty string hardware setups.

•Clevis pins & cotter pins (for securing the plate to clevis/socket tongue).
•Hex nuts & washers (for fastening to transmission tower structures).
•Anti-corrosion grease (for pin connection lubrication and rust prevention).
•Insulator mounting brackets (adapters for different insulator types).
