• Manufactured according to standard IEC-61238-1-3
• Direct factory from China
Shear Head Bolts
• Material: Tin-covered aluminum alloy with a high-lubricity coating.
• Design: Equipped with three hexagonal shear-head bolts that break off at a predetermined torque.
• Function: Ensures consistent installation torque, preventing over-tightening and potential conductor damage.
Long Palm (Handle)
Material: Tin-plated aluminum alloy.
• Design: Extended palm provides a larger surface area for better grip and load distribution.
• Function: Enhances mechanical stability and durability of the connection.
Long Barrel
• Material: Tin-plated aluminum alloy.
• Design: Cylindrical section accommodates conductor sizes ranging from 185 mm² to 400 mm².
• Function: Increases contact area to minimize resistance and improve electrical conductivity, especially beneficial for larger conductors requiring higher tensile strength.
3. Applications
• Overhead LV & MV power lines (transmission & distribution), suitable for both aluminum and copper materials
• It can be connect to a flat bar or equipment pads equipped with 2-hole spacing for low and medium voltage applications up to 36 kV
• They are suitable for both outdoor and indoor use, available with various palm hole sizes. Used for Power Systems, Industrial & Utility Networks, Renewable Energy and etc.
4. Installation Guide
• Prepare the Cable
Cut the cable straight.
Strip the insulation to expose the conductor.
• Loosen Bolts
Slightly loosen the shear bolts for easier cable insertion.
Never remove them completely—this can damage threads.
• Insert the Conductor
Push the stripped cable fully into the barrel until it stops.
•l Tighten Until Bolts Snap
Use a wrench to tighten each bolt one by one.
Stop when the bolt heads shear off—this means proper torque is reached.
• Final Check
Ensure all bolt heads have snapped off.
Confirm the cable is securely clamped and won’t pull out.
