The main characteristic of the flame-retardant control cable is that the cable is not easy to ignite or the fire retards when the fire is only limited within a certain range, and it is suitable for the occasion with high requirements for the flame retardant performance.
The main characteristic of the fire-resistant control cable is that in addition to being able to transmit power under normal working conditions, the cable can maintain normal operation for a certain period of time when it ignites and burns, and is suitable for occasions where fire resistance characteristics are required.
Second, the product standard This product is organized according to GB9330-1988 standard production, but also according to user requirements of other standards.
In addition to the flame-retardant cable according to the above standards, its flame retardant performance is divided into three different flame-retardant categories A, B, and C according to the provisions of GB/T 18380.3-2001, and the flame retardant performance of the A-class category is optimal. According to the need to use.
The fire-resistance performance of fire-resisting cables should conform to GB/T 19216.21-2003

Fire-resistant cable models add N to common control cable models
Fourth, product use characteristics 1. The rated voltage Uo/U is 450/750V.
2. The long-term allowable working temperature of the cable conductor is 70°C.
3. The laying temperature of the cable should not be lower than 0°C. The recommended allowable bending radius is as follows:
Unshielded cables should not be less than 6 times the outer diameter of the cable.
Cables with armoured or copper tape shielded construction shall be not less than 12 times the outside diameter of the cable.
The flexible cable with a shield structure should not be less than 6 times the outer diameter of the cable.
Aluminum Ultra Flat Sheet is a special kind of Aluminum Sheet.It has high standard on surface flatness.As a result Aluminum Ultra Flat Sheet is suitable using in the electronic products surface parts or those application which has high requirement regarding the surface conditions.The advantage of aluminum sheet is as follows:
1. Easy to process.
2. Good conductivity and thermal conductivity.
3. The density is small.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
