Suitable for automatic control, monitoring circuit, protection circuit and other systems of power frequency AC rated voltage 0.45 / 0.75kV and below
Rated voltage
The power frequency AC rated voltage is 0.45 / 0.75kV, and the highest voltage of the AC system should not exceed 1.0kV.
Laying indoors in industries such as metallurgy, electric power, construction, etc., where shielding and good mobility are required.
Operating temperature
The long-term allowable maximum working temperature of the cable conductor is 70 ℃; when short-circuited, the maximum temperature of the cable conductor does not exceed 160 ℃, and the duration does not exceed 5s.
Ambient temperature
The minimum working environment temperature is -15 ℃.
Laying temperature
The laying temperature of the cable should not be lower than 0 ℃.
Bending radius
The minimum bending radius should not be less than 6 times the outer diameter of the cable.
Package
The coiled or coiled cable should be neatly wound and properly packed on the reel. The cable ends should be reliably sealed, and the cable ends that extend out of the reel should be protected by a protective cover. The cable packaging should be accompanied by a label indicating: manufacturer’s name, type, specifications, rated voltage, length, quality, manufacturing date, standard number or certification mark, the correct rotation direction of the cable reel, etc.
Transportation
Transportation is generally in the form of vehicles and ships. The cables must be firmly fixed during transportation to avoid damage to the cables or appliances caused by collision or overturning. The cable reel must not be laid flat. During transportation, it is strictly prohibited to drop the cable reel with cables from a high place.
Storage
The finished cable should be stored in an environment with a temperature between 0 and 40 ° C and a humidity of less than 85%. It should not be exposed to direct sunlight or rain, and should be properly ventilated to keep the environment dry. The cables can be generally be used for more than 25 yearsare stored and used according to the above requirements.
Installation instructionsDuring installation, the ambient temperature should not be lower than 0 ℃. If the thermometer test ambient temperature is lower than 0 ℃, the cable should be preheated before preparing for installation; the bending radius during the cable laying process should be strictly controlled to avoid causing internal mechanical injury. The yellow / green double-colored insulated cores should be connected according to the specified positions.
