Clamps and Connectors for EHV Sub-station

The performance of the connector depends on proper installation of the connectors to achieve this we will be enclosing erection instructions along with the connector packing.

3. Torsional movement

2. Horizontal movement.

1. Vertical movement. 

Swivel type spacer clamp (semi flexible) will permit movements between conductors.

Rigid type spacer clamp-will not permit any relative movements between conductors.

The spacer clamp designed for twin and quadruple Conductors are rigid type / swivel type as per customer requirements. And test will be conducted as per I.S 10162.

                        4.   Radio interference test under dry & wet conditions.

                        3.   Visual corona test under dry & wet conditions.

2.   Short time current with stand test for the rated fault conditions

                        1.   Temperature rise test for continuous current ratings.

The following test will be conducted at independent lab to validate our design. (Type test)

-2-

6.     Galvanizing test.

5.     Tensile / Slip test.

4.     Resistance test. (Millivolt drop test)

3.     Temperature rise test for continuous current ratings.

2.     Dimensional check.

1.     Visual inspection.

In order to ensure the required electrical, mechanical and corrosion resistance characteristics, the following tests are carried out at our works on power connector as per I.S 5561.

                  

3.     Finished product.

2.     In process

1.     Raw material

The connectors offered are as per our standard manufacturing quality plan consisting of the following stages:-

The connectors manufactured are generally bolted type. Welded / compression type connector also can be developed / supplier. 

The connectors designed for the system voltage of 220kV and above are self shielded type, free from visual corona and RIV will be within the limits as per standard / specifications.

For expansion connector, the flexible will be copper (tinned) or Aluminum Laminations for up to 132kV.  For 220kv and above AAC standard conductors are welded (Aluminum welding) to the body of the connector.

Wherever Aluminum to copper connections are required, Al. Cu. Bimetallic sheet are too used to avoid galvanic corrosion.

                  

The connector material shall be Al. Alloy 4600-(A6) to 617. For the Aluminum bus bar-substation & Brass grade 3 to I.S 292 / Al. Bronze grade AB2 to I.S 305 for copper bus bar-substation. The fasteners are Mild Steel to I.S 1363 & hot dip Galvanized as per I.S 2629 / Stainless Steel grade A2-70 as per customer requirements / Specification.

                  

The connectors are designed as per I.S: 5561-1975 & can be designed to B.S: 159, NEMA CC1 & other any standards / customers specification.
