Technical Data & Available Versions

GENERAL DESCRIPTION 

To satisfy the needs of the Utility Companies and a segment of Industrial customers, WESCOSA has developed a 17.5kV, 25kA Switchgear conforming to IEC standards.

The Switchgear utilizes Tamco’s VK series of Vacuum Circuit Breakers with world-renowned Cutler-Hammer Vacuum Interrupter.

CERTIFCATION AND APPROVAL

Conforms to IEC Specification 60289 and subjected to Type Test in KEMA, Netherlands, including arc resistance test at 25kA.

CONSTRUCTION 

Typical cross-section and overall dimensions of the switchgear are shown in Fig. 1. As standard, all exterior and interior parts are painted with ANSI 61, Light Grey paint, applied through electronic deposition. Units  have provision to enable them to be bolted together to form a rigid freestanding assembly and are designed to permit extension on either side in future.

Each vertical structure consist of the following:

1. VCB Compartment
2. Bus Bar Compartment
3. Low Voltage Compartment
4. Potential Transformer Compartment (For incoming and bus Tie units only)
5. Cable Compartment

1.     VCB COMPARTMENT

This compartment accommodates the vacuum circuit breaker. Circuit breakers are available with continuous current rating of 630, 1250 and 2000 Amperes. Movement of VCB inside the compartment is by means of racking mechanism, which is operable with the front door of the compartment closed. Comprehensive interlocks are provided to ensure the following:
