Guy grip dead end
Guy grip dead end is made of the same basic material as the strand to which it is applied.Common materials are galvanized steel wire and aluminum-clad steel wire .It is intended to design for use on single pole associated with distribution constraction.The product grips the strand uniformly to preven distortion of the strand and the grip strenth is not less than 100%UTS of the strand.During installation,care should be taken to ensure a successful installation .This product is intended for use by trained crafts people only.

what is preformed dead end?
In order to increase the grip foce of the preformed rod on the strand or conductor,several preformed rods glued together according to the need,and the part in contact with the strand is gritted.
A certain length in middle of the glued preformed rod need to be wrung to facilitity the installation of the thimble clevis,based on the center of the wrung segment,the preformed rod is folded in half according to the required radius to form twe legs.The product that makes after such craft processing is called preformed dead end.
Preformed dead end is widely used in power transmission and distribution lines.Its main function is to tighten the conductor and install it on the terminal tower.It bear the line operating tension and other additional loads.For various categories of conductor,strand,or optical cable etc,different occasion,to desigh different categories of preformed dead end production.Because of its special structure,compared with the traditional bolt or compression tension clamp,has excellent product performance:
1,The stress of clamped conductor is evenly distributed along the wrapping conductor segment to ensure the grip forth on the conductor and avoid the damage to the conductor caused by stress concentration.
2,The clamp stracture installed on the conductor can enhance the vibration resistance of the conductor and extend the service life of the conductor.
3,Installation is convenient,the construction personnel only needs to ensure that the clamp is evenly wound around the conductor,without any tools,installation quality is easy to ensure.
