Example:
KYJEE-WD-ZR means copper conductor cross-linked polyolefin insulated polyolefin sheathed low smoke non-halogen flame-retardant control cable.
RYJEEP-WD-ZR means copper conductor cross-linked polyolefin insulated polyolefin sheathed copper wire braid shielded low smoke non-halogen flame-retardant flexible cable for connection.
YJEE22-WD-NH means copper conductor cross-linked polyolefin insulated polyolefin sheathed steel tape armored low smoke non-halogen fire-resistant power cable.
- Description of the purpose and usage properties
The cable is used for power distribution, electrical connection, electrical instrument and signal transmittal and control of electronic apparatus in high rises, subway and other large public facilities.
The maximum permitted long-term operating temperature of the polyolefin insulated cable shall be 70¡æ, and 150¡æ for cross-linked polyolefin insulated cable.
The permitted bending radius of the cable with copper tape shielding or steel tape armoring shall not be less than 12 times of the outer diameter of the cable, and 6 times for all the other types of cables.
