Functions of various cables

2020-06-06
RVV: (227IEC52/53) PVC insulated flexible cable (cross-sectional area: 0.5-6.0 core wire number 1-24)
Uses: power cord, signal line, household appliances, small electric tools, instruments and power lighting, etc. As long as this specification line meets the national standard, the price is not much different, but there is no shortage of useful impurities in the market, insufficient wire diameter, short meters, and direct placement (core wire copper wire is not twisted or core wire is untwisted, so the tensile capacity is greatly reduced, Resistance increase) to charge. Derived model: RVVS: The twisted pitch encryption of the core wire of this model is generally used in broadcasting systems.

RVVP: Copper core PVC insulated and shielded PVC sheathed flexible cable, voltage 300V/300V 2-24 core. Main quality indicators: wire diameter (including core wire and braided wire, the thicker the better, the impurity copper is made thicker to meet the resistance standard), copper core purity, braided density, lay length. Uses: instruments, meters, intercom, monitoring, control installation.

RVS and RVB are suitable for power cords for household appliances, small electric tools, instruments, meters and power lighting connections. RVS can also be used for broadcasting lines or replacing RVV lines. RVB can replace the gold and silver wire when the requirements are not high.

RG: Physical foamed polyethylene insulated access network cable is used to transmit data analog signals in the coaxial fiber hybrid network (HFC). This is an American standard and is approximately equivalent to the national standard SYWV series. Main quality indicators: copper core wire diameter, insulation thickness, braided material (mostly aluminum-magnesium wire braided on the market, tinned copper should be used for good quality), braided density.

UTP: LAN cable uses: transmission of telephones, computer data, fire protection, anti-theft security systems, intelligent building information networks. Commonly used UTP CAT 5, UTP CAT 5E shielded model is STP.

KVVP: PVC sheathed braided shielded cable Uses: signal transmission, control, and measurement of electrical appliances, instruments, and power distribution devices.

AVVR: Flexible cable for PVC sheath installation (cross-sectional area: 0.12-0.5 core number 1-24) Uses: signal, control. Such as access control signal, control, PTZ control, etc.

RV, RVP PVC insulated cable, PVC shielded cable, mainly used for equipment.

BV, BVR PVC insulated cable Uses: Suitable for electrical instrumentation equipment and power lighting fixed wiring, affordable and low resistance. In many occasions connected to the power supply can be considered.

RIB: Speaker cable (fever line, gold and silver line) Some audio cable models are often marked with "6N" and "7N", which is used to indicate the purity of the fever line made of metal materials. For example, "99.9999%" can be expressed by "6N", which means that the purity is 6 nines. The larger the number in front of N, the higher the purity of the audio line. Whether the audio equipment of the home theater needs to use a higher quality audio line, the key is to master the principle of seeking truth from facts and doing what you can. For generally popular audio equipment (less than 10,000 yuan), there is no need to deliberately pursue the high quality of the wire, as long as the copper core signal line with a larger cross section is generally used. For better home theater audio equipment, you can consider using high-quality audio cable.

HYV, HYA data communication cable (indoor and outdoor) (core diameter 0.5mm, core number 2, 4, 8 etc.) namely telephone line, used for telephone communication and radio equipment connection and distribution box of telephone wiring network For wiring etc. The diameter of the core wire on the market is generally 0.4 mm, and it is almost the same as steel wire or copper-aluminum alloy. In addition, the phone line generally has insufficient meters.

SYWV (Y), SYKV cable TV, broadband network special cable structure: (coaxial cable) single oxygen-free round copper wire + physical foamed polyethylene (insulation) + (tinned wire + aluminum) + polyvinyl chloride (poly Ethylene), (equivalent to the American standard RG-6, RG-59). Nowadays, aluminum-magnesium wire is commonly used in the market (can not be welded, easy to oxidize), the core wire is copper-clad aluminum, copper-clad steel, and even many people think that SYWV wire is cheaper than SYV wire, but in fact it is not so.
