Supply high quality RVV control cable.
RVV control cable is known as copper core PVC insulated PVC sheathed flexible cable. It is also known as light polyvinyl chloride sheathed flexible cable, referred to as soft sheathed cable, is a kind of sheathed cable.
Because it is a soft core, RVV is generally used in narrow areas or places where it needs to be bent frequently. Mainly used in electrical appliances, 미터, electronic equipment, and automation devices with power lines, control lines, and signal transmission lines, specifically for burglar alarm systems, building intercom systems, 등.
Rated working voltage: 300/500다섯
The long-term allowable working temperature of the cable is not higher than 70℃.
The maximum temperature of the cable conductor in case of a short circuit (the longest duration does not exceed 5s) does not exceed 160℃.
The ambient temperature when the cable is laid should be no less than 0℃, 그렇지 않으면, it needs to be preheated beforehand.
ㅏ) The cable without an armor layer should be not less than 6 케이블 외경의 곱.
비) Cable with an armored or copper tape shielding structure should be not less than 12 케이블 외경의 곱.
기음) flexible cable with shielding structure, should be not less than 6 케이블 외경의 곱.
RVVP is a kind of cable with soft conductor PVC insulation plus a shield and PVC sheath. Copper-core PVC insulated shielded PVC sheathed flexible cable, also known as electrical connection anti-interference flexible cable.
The “P” in RVVP refers to shielding, that is to say, RVVP wire has a shielding layer, and RVVP has a stronger anti-interference ability for external signals.
Rated voltage 300/300V, the number of cores commonly used is 2-19 코어.
Commonly used core wire diameter: 0.3 square, 0.5 square, 1 square, 1.5 square, 2.5 square, 4 square.
The role of cable shielding is mainly to prevent the interference of external interference sources to the cable itself and the interference caused by the cable to other circuits. The use of a shielded cable and reliable grounding of the shielding layer is an effective measure to suppress its electromagnetic interference.
It is suitable for communication, 오디오, broadcasting, audio systems, burglar alarm systems, intelligent automation systems, automatic meter reading systems, fire-fighting systems, and other needs to prevent interference line connection, efficient and safe transmission data cable.
The service life of control cables is determined by the air oxidation induced period of the sheath raw materials. 그만큼 general control cable is designed to be used for 20 연령, which is the maximum life span of the control cable. Although it is possible to go longer in specific daily life, the design duration is the maximum life of control cables from a safety point of view.
The elements that endanger the life of the control cable and the way to increase the life of the control cable.
