Electrical Power Fitting-Suspension Clamps for Overhead Lines
Function
A:
Suspension clamp is used to suspend the ADSS cables on the straight poles/towers.
Characteristics of suspension clamp
(1)Suspension clamp has greater interface with ADSS cables. Stress is distributed equally without stress focus. It can protect optical cables very well and can improve the intensity of cable line installation point.
(2)Suspension clamp has higher supporting capability of dynamic stress. It can supply enough grip strength (14%RTS)in order to ensure the safety of ADSS cables under imbalanced load for long time.
(3)The gentle rubber clamp pieces improve self-damping and reduce abrasion.
(4)The smooth shape of the ends improve the discharging voltage and reduce the loss of electric power.
(5)The superior aluminum alloy materials have higher comprehensive mechanical performance and corrosion resisting capability, which extends the lifetime usage.

B:
Technical requirement of suspension clamp
Conforming to the technical specifications and test methods of DL/T767-2003 preformed helical fittings for ADSS
Ordering instructions
(1)Choose the right type suspension clamps according to the parameters(such as operating span, diameter, rated tensile strength) of the ADSS cables.
(2)Collocation: One set/straight pole or tower
(3)The inner armor rods should be longer if the corona coil and vibration damper are installed.
(4)Intensity: 30kN\50 kN\70 kN.
