Application and Description：
These cables are used for internal wiring of switchboards and distribution boards at AC voltages up to 1000V or
DC voltages up to 750V. They are generally installed in ducts and are used for internal wiring of equipment with
an operating temperature of 90°C. They are suitable for use in public places (such as government buildings, etc.)
where smoke and toxic gases may cause threats to life and damage to equipment. This cable does not produce
corrosive gases when burned, which is particularly important for electrical equipment.
