Ground Rod comes in three different types of various diameter and length and has a cone

point for easy driving.

The Plain Rods are used with ground rod clamps for proper electrical contact.

The Soldered type has five turns of #12 soft annealed copper wire soldered at the upper end.

The Electro-weld type has a 3/8 Inch round bar welded to the upper end portion of the rod.

Length and distance of pigtail from upper end of the rod.

Eight point top plate blade expands with

the base plate upon screwing the anchor rod down

to form a cone shaped square which distribute the

anchor’s holding power into the ground.

FORGED EYE SHAFT

SCREW ANCHOR

Hot Dip Galvanized

Forged Eye Shaft Screw Anchors can be

installed manually by inserting a bar through the eye

and screwing the anchor down

ANCHOR ASSEMBLY

Hot Dip Galvanized

Forged Thimble eye, Twin Eye and Triple Eye

Anchor Rods are used for guying with expanding,

cross plate, cone and screw anchors as well as

anchor log assemblies.

GUY ATTACHMENT

Hot Dip Galvanized

Guy Attachment provides an economical

and efficient means of fastening guy to pole, either

steel or wood poles.

The press formed steel guy attachment has a well

rounded strand groove that would protect the strand

from damage.

Hot Dip Galvanized

Eyelet are drop forged from rolled basic open

hearth steel and are compatible with the strength of

the bolts used with them.

Angle Thimble Eyelet are used for down guys and

straight thimble eyelet is used for span guys.forged steel Guy Attachment are

designed for direct pole installation for glass and

wood strain insulators.

Tension Clamp For Aluminium Conductor
                TECHNICAL SPECIFICATION
1. SCOPE
    This specification covers the design and construction of Tension of Tension Clamps to be used for the termination of aluminium-conductors at terminal poles and section poles.
     The Clamps are suitable for used in Tropical zone, with a maximum ambient temperature of approximately 40ºC and a mean annual temperature of approximately 28ºC with high humidity and heavy rainfall.
2.             STANDARD
this specification is make reference to and comply with the requirements of following standard:
BS 3288:1973 – Insulator and Conductor fitting for
                  Overhead Power Lines
BS 729         – Hot dip Galvanised
3.             ELECTRICAL SYSTEM
The Clamps will be designed for use on a 3 phase,3 wires, 33/22/11/6.6kv,50 Hz, primary distribution system with the star-point of the source-end transformer earthed through an Earthing Resistor.
4.             DESIGN AND CONSTRUCTION
The Clamps are manufactured from material which is not cause chemical corrosion when in constant contact with aluminium conductor. They are have a tensile strength that the breaking strength that are not less than the breaking strength of the conductors to be connected.
The Clamps are properly designed such that will not cause any unnecessary strain and abrasion on the surface of conductors.
5.             SIZE OF CLAMPS
The Clamps aredesigned to accommodate the following sizes of Aluminium conductors:
a.                 50mm² Alu. Conductor
b.                 100 – 150mm² Alu. Conductor
6.             MARKINGS
The Tension Clamps will be indelibly marked as Customer Requirment.

7. INSPECTION AND TESTS
For evaluation purposes, we will supply the following items to our cusotmer
a. A sample of the Tension Clamp complete with all accessories.
b. A copy of the test report on tests conducted in accordance to BS 3288 and BS 729
