Description
CTV-32 Cable Test Van is a complex solution for preliminary and accurate location of faults in power cables, as well as their subsequent high voltage tests.
CTV-32 offers a comprehensive solution designed for testing cable lines within the voltage range of 0.4 kV to 10 kV, accurately providing pinpoint areas of cable faults. Structurally, it encompasses both an operator’s compartment and a dedicated high-voltage compartment.
A distinct control rack serves as the demarcation between the operator’s compartment and the high-voltage section. This control rack hosts essential control components of the test van, alongside display elements that facilitate real-time monitoring of test parameter values. The rack is also equipped with sliding drawers for storage of additional equipment or tools.
At the request of the Customer, the CTV-32 can be supplemented with additional equipment in accordance with the requirements.
