Paired control cables
Twisted Pair Signal Communication Control Cable consists of two insulated wires twisted around each other, designed to effectively transmit analog and digital signals. Its unique twisting design not only reduces electromagnetic interference, but also ensures high fidelity and stability of the signal. According to the different shielding designs, twisted pair cables are mainly divided into the following two types:
•Unshielded Twisted Pair (UTP): Suitable for environments with relatively low requirements for anti-interference, with the advantages of high cost-effectiveness and easy installation.
•Shielded Twisted Pair (STP): A shielding layer is added to the outside of each pair of wires to provide stronger anti-interference capabilities and is suitable for high-noise environments.

Standard:
Twisted pair cables must comply with multiple international standards to ensure their performance and reliability. For example, IEC 61156-7:2023 specifies the requirements for symmetrical twisted pair cables with transmission characteristics up to 1200MHz, which is suitable for various digital and analog communication systems. In addition, the ISO/IEC 11801 standard defines different categories of twisted pair cables, such as Category 5e, Category 6, etc., which are suitable for different frequency ranges and application scenarios.
Application areas：
Network communication: used to connect computers, switches, routers and other devices to build local area networks (LAN) and wide area networks (WAN).
Video transmission: in video surveillance systems, twisted pair cables can be used to transmit high-definition video signals to ensure real-time and clarity.
Audio transmission: used for signal transmission between high-fidelity audio devices to ensure pure and stable sound quality.
Industrial control: in automation systems, twisted pair cables are used to transmit control signals and data to ensure reliable operation of the system.
Automotive electronics: used for data transmission between in-vehicle infotainment systems, navigation systems and other devices to improve user experience.
Aerospace: in spacecraft and satellite systems, twisted pair cables are used to transmit high-speed data to meet reliability requirements in harsh environments.
Product Performance
Bandwidth and Transmission Rate: Depending on the category, the bandwidth and supported transmission rate of twisted pair cables vary. For example, Category 5e cables support up to 100MHz bandwidth, suitable for 1000Mbps data transmission.
Transmission Distance: Standard twisted pair cables usually have a maximum transmission distance of 100 meters without the use of repeaters. Beyond this distance, you may need to use a repeater or choose a low-attenuation cable type.

Want to learn more? Check out our electrical cable most frequently asked questions.
KVV Cable Selection Problem
How to choose the right conductor cross section? The choice of conductor cross section mainly depends on the size of the load current. The larger the current, the larger the conductor cross section should be to ensure the current carrying capacity of the cable.
How to choose the right number of cores? The choice of the number of cores depends on the complexity of the circuit. The more devices that need to be connected in the circuit, the more cores should be.
How to choose the right insulation level? The choice of insulation level depends on the working voltage. The higher the voltage, the higher the insulation level should be.
How to choose the right sheath material? The choice of sheath material depends on the laying environment. If the environment is harsh, such as high temperature, high humidity, corrosiveness, etc., corrosion-resistant and high-temperature resistant sheath materials should be selected.
KVV Cable Installation Problem
What is the bending radius of KVV cable? The bending radius of KVV cable is generally not less than 6 times the outer diameter of the cable, and for cables with armored or copper tape shielding structures, it is not less than 12 times the outer diameter of the cable. Too small a bending radius will damage the cable and affect its service life.
What are the requirements for the laying environment of KVV cable? The laying environment temperature of KVV cable should not be lower than 0℃. If the ambient temperature is below 0℃, the cable should be preheated. Avoid sharp-angle bending, extrusion and other mechanical damage during laying.
How to deal with the joints of KVV cables? The joints of KVV cables should use special joints and be connected according to the prescribed process to ensure that the joints have good electrical performance and mechanical strength.
Problems with the Use of KVV Cables
What is the rated temperature of KVV cables? The rated temperature of KVV cables is generally 70℃. Long-term operation exceeding the rated temperature will accelerate cable aging and shorten the service life.
Can KVV cables replace RVV cables? Although KVV cables and RVV cables are both control cables, they cannot be replaced at will due to different structures and performances. Generally speaking, RVV cables cannot replace KVV cables, but KVV cables can replace RVV cables under certain conditions.
What are the reasons for KVV cable failure? There are many reasons for KVV cable failure, the most common of which are: insulation aging, mechanical damage, overload, short circuit, poor joints, etc.
Other Issues
What is the flame retardant performance of KVV cables? Some KVV cables have flame retardant properties, but not all KVV cables have flame retardant properties. If there is a requirement for flame retardant properties, flame retardant KVV cables should be selected.
How long is the life of KVV cables? The life of KVV cables is related to factors such as the use environment, load current, and laying method. Under normal circumstances, the normal service life is 15-20 years.
