Kyn61-40.5 Steel-Clad Removable-Type AC Metal Enclosed High Voltage Switchgear
Product Overview :
KYN series metal-clad removable enclosed switch cabinet (called
switch cabinet for short). It is applicable for power receiving and
distribution in the 3.6-12Kv three-phase AC 50Hz single bus bar and
single bus bar sectioning system. It has the functions of
controlling, protecting and monitoring the circuit.
Features:
The switch cabinet is metal-clad. Its structure design accords with
the standards GB3906-91, IEC298, DL404 and DL402. The crust
structure is made of steel plates by means of bending and welding,
which are joined by bolts. The hand buggy panel is the door of
cabinet. The bosom of switch cabinet is divided into a breaker
chamber, a main bus bar chamber, a cable chamber and a relay
chamber by metal partitions. The degree of protection of the entire
crust and compartments is IP2X equally. All the metal structures
are connected to ground reliably. All the compartments of main
circuit system have pressure release channels for independent
exhaust.
