Double Layer Preformed Dead End

Alright, here's the deal. A double layer preformed dead end is basically the heavy-duty version of the single layer. You use it when the span is long, the wind is strong, or the line voltage is up there - think transmission lines, not neighborhood feeders.

It's got two layers of preformed rods wrapped around the conductor. That second layer isn't just for show. It adds grip, spreads out the stress, and gives you way more holding force. You still don't need bolts, clamps, or hydraulic tools. Just wind it on and hook it up. If your job calls for serious tension, this is what you grab.

Features

Double-layer preformed wire structure - The inner layer grips the conductor while the outer layer bears the tension; the combined action of the two layers provides higher holding strength than a single-layer design.

No bolts or crimping - Like the single-layer version, it requires no special tools or torque wrenches.

Anti-slip inner coating - Provides a firm grip without damaging the conductor's aluminum strands.

Corrosion-resistant materials - Made of aluminum-clad steel or aluminum alloy; withstands salt-spray environments.

UV-resistant - Does not crack or become brittle after twenty years of outdoor exposure.

Compatible with various conductor types - Suitable for ACSR, AAAC, AAC, and ACAR.

Re-installable - Can be removed and re-installed once or twice without issue (though this is not standard practice).

Superior fatigue resistance - The helical structure naturally absorbs aeolian vibration. The double-layer design adds a second buffer, offering much better fatigue resistance than rigid clamps.

Significant vibration damping - Handles typical vibration scenarios without needing additional vibration dampers (though installation is recommended for extreme conditions).

Efficient installation - Takes slightly longer than the single-layer version but is still much faster than compression-type clamps.

Zero maintenance - Once installed, it requires no further attention; no need to periodically tighten bolts.

Suitable for high-tension applications - Ideal for long spans, major crossings, and areas prone to heavy ice or strong winds.

High safety margin - Even if the outer layer is damaged, the inner layer can still hold for a time, providing a window for maintenance.

Suitable for long spans, river crossings, and high-wind areas.
Double-layer preformed tension clamps are designed for these challenging applications:
Long spans - Lines exceeding 300 meters, such as those across open plains or valleys.
River/valley crossings - High towers at both ends and large spans result in concentrated tension; the double-layer design provides an adequate safety margin.
High-wind areas - Lines in coastal regions, wind corridors, or typhoon paths; double-layer clamps offer significantly superior resistance to wind-induced vibration.
Heavy icing areas - Locations with thick winter ice accumulation increase the load on the conductor, requiring robust holding strength.
High voltage levels - 69kV, 138kV, 230kV, and 500kV; double-layer clamps are the standard choice for these major transmission networks.
Simply put, if a location demands uncompromising reliability, use the double-layer version.

This Double Layer Preformed Dead End is compatible with a wide range of conductors:
ACSR (Aluminum Conductor Steel Reinforced) - The most common type; fully compatible.
AAAC (All Aluminum Alloy Conductor)
AAC (All Aluminum Conductor)
ACAR (Aluminum Conductor Aluminum-Alloy Reinforced)
When selecting the product, you only need to provide three details:
Conductor model (e.g., ACSR 795 kcmil 26/7)
Conductor outer diameter (in millimeters or inches)
Rated tensile strength (or the conductor specification sheet)
We will match the clamp size to your specific conductor, ensuring it is ready for immediate installation.

"Used these on a 138kV river crossing. Held solid through two storms. Beats compression hands down."

Had a 400-meter span that kept slipping with single layer. Double layer fixed it."
-- Dave, Montana

"River crossing on a 230kV line. These held like anchors."

Q: How do you ship? How long does it take?
We ship by sea, air, or express - whatever works for you. Sea freight to the US usually takes 25–35 days. Air or DHL/FedEx is about 5–7 days. Small orders we can ship within 48 hours.

Q: What payment methods do you accept?
T/T (bank transfer) is the most common. For first-time orders, we typically ask for 30% deposit and 70% before shipment. For repeat customers, we can be more flexible. We also accept L/C, PayPal, and Western Union on smaller orders.

Q: How do you pack the dead ends?
Standard is carton boxes with inner poly bags to prevent moisture. For large orders, we pack cartons onto wooden pallets, then shrink-wrap and strap them.
