Use Description
Heliformed Suspension clamp is intended for use on aluminum based conductors, Aluminum Coated Steel Conductor and galvanized steel strands. It is designed
to reduce the static and dynamic stresses at the support point, so that the conductor or strand is protected against the effects of oscillations.
It also protects the conductor in the support against impulse and power flash-over.

Application
1. For the reduction of static stresses at conductor suspension points and to provide greater protection to conductors against the dynamic stresses of Aeolian vibration.
2. To give conductors protection against impulse and flash-over.
3. To protect conductors against abrasion, bending and compression stresses. The protection offered by heliformed suspension clamp fittings is superior to armor-clamp combinations.
4. To install line angles up to and including 30° and, through use of double units, up to 60°.
5. For proper performance and personal safety be sure
to select the proper size with preformed Armor Rods and clamps according the conductors size before application.
6. Dead ends are precision devices. To insure proper performance, they should be stored in cartons under cover and handled carefully.
7. If you have any question please contact with TANHO Electrical Equipment Co., Ltd.

Safety Considerations
1. This product is intended for a single (one-time) use and for the specified application.
