The purpose of outdoor water blocking lines

1、 Definition and characteristics of outdoor water blocking lines Outdoor water blocking line is a type of electrical wire specifically designed to provide protection for electrical equipment and circuits in outdoor environments. Its characteristic is excellent waterproof performance, which can withstand the erosion of natural factors such as wind, rain, sun, and rain in outdoor environments, and avoid the occurrence of moisture, oxidation, and other situations on the wires. At the same time, it also has characteristics such as temperature resistance, wear resistance, and weather resistance, and can work stably for a long time in outdoor environments. 2、 The application scope of outdoor water blocking lines Outdoor water blocking lines are mainly used in the following scenarios: 1. Outdoor lighting system: such as street lights, landscape lights, etc. 2. Power equipment: such as switchgear, box transformers, cable trays, etc. 3. Communication equipment: such as telephone poles, television antennas, etc. 4. Security equipment: such as surveillance cameras, turnstiles, etc. 5. Other outdoor equipment: such as billboards, signage, etc. 3、 The advantages of outdoor water blocking lines The use of outdoor water blocking lines has the following advantages: 1. Protect electrical equipment from natural factors such as rainwater and moisture, and extend the service life of electrical equipment; 2. Prevent safety accidents such as short circuits and leakage of electrical wires, and ensure personal and property safety; 3. Possess good weather resistance, temperature resistance, wear resistance and other characteristics, and adapt to complex outdoor environments; 4. It is easy to install, has a long service life, and is economical and practical in maintenance and replacement. 4、 Precautions for selecting outdoor water blocking lines When selecting outdoor water blocking lines, the following points should be noted: 1. Choose products with excellent waterproof performance to ensure that the wires work properly in complex environments; 2. Confirm that the temperature resistance and wear resistance of the wires meet the actual requirements; 3. Choose products produced by legitimate manufacturers to ensure reliable quality; 4. Reasonably select and match the size and length of the wires according to the usage requirements; 5. Follow electrical safety regulations and operating procedures, and correctly install and use outdoor water blocking lines. 【 Conclusion 】 Outdoor water blocking wire is a type of wire with excellent waterproof performance. Its application can ensure the normal operation of electrical equipment, avoid safety accidents, and have good durability and economy. When selecting and using, attention should be paid to safety and regulations to ensure the normal operation of outdoor electrical equipment.

The difference between RVV and RVVP


RVV wires and cables and RVVP, RVV refers to unshielded sheathed power lines, and RVVP refers to shielded sheathed power lines. P represents shielding, which means that RVVP has an additional layer of shielding layer (aluminum foil+shielding mesh) compared to RVV, with the main effect of anti-interference (external signal interference). The specific choice between using RVV or RVVP should be based on the performance of the wires and cables and the required usage. 1. Different definitions The full name of RVV cable is copper core PVC insulated PVC sheathed flexible cable, also known as lightweight PVC insulated polymer, commonly known as soft sheathed wire, which is a type of sheathed wire. RVV wires and cables are two or more RV wires with an additional layer of sheath. RVV wires and cables are the most commonly used cables in weak current systems, with an indefinite number of core wires, two or more, and a PVC sheath on the outside. There are no special requirements for the arrangement of core wires. The letter R represents flexible wire, and the letter V represents insulated polyvinyl chloride (PVC), The full name of RVVP is copper core polyvinyl chloride insulated polyvinyl chloride sheathed shielded flexible cable, where R represents flexible wire; V polyvinyl chloride insulation; V polyvinyl chloride sheath; P shielding. RVVP is a type of cable with a soft conductor PVC insulated wire and a shielding layer and PVC sheath. It is a copper core PVC insulated shielded PVC sheathed soft cable, also known as an electrical connection anti-interference soft cable. Rated voltage 300/300V. 2. Different colors RVV is black and white. RVVP is black. 3. Different uses RVV wires and cables are mainly used for power lines, control lines, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices. They can be specifically used for anti-theft alarm systems, building intercom systems, household lighting connection lines, etc. RVVP is suitable for communication, audio, broadcasting, audio systems, anti-theft alarm systems, intelligent automation systems, automatic meter reading systems, fire protection systems, and other data transmission cables that require anti-interference line connections and are efficient and safe. The advantage of RVVP is to minimize the interference of external signals.

What is the difference between a fire line and a regular line


1、 The material of fireproof wire is different from that of ordinary wire Fireproof wires are usually made of flame-retardant materials, which can effectively slow down the speed of wire burning, thereby reducing the occurrence of fires. Ordinary wires may not necessarily be made of flame-retardant materials. 2、 The structure of fire lines is different from that of ordinary lines The structure of fire wires usually adopts a double-layer insulation structure, and the space between the inner and outer layers can reduce the heat generation and heat transfer rate of the wires. This structure can effectively reduce the heat and duration generated by electric sparks, and reduce the possibility of fire. Ordinary wires only use a single-layer insulation structure. 3、 The safety performance of fire wires is different from that of ordinary wires Due to the fire resistance of fire wires, the internal fireproof materials can effectively suppress the generation of electric sparks and prevent the occurrence of fires in the event of wire failure or overload. When ordinary wires experience faults or overload, they are prone to generating electrical sparks inside, which can easily lead to fires. In summary, there are differences in materials, structure, and safety performance between fireproof wires and ordinary wires. Choosing fire prevention lines can effectively prevent the occurrence of fires and improve the safety performance of electrical equipment. Therefore, when selecting wires, suitable fire-resistant or ordinary wires should be selected according to the actual situation to ensure the safety of life and work.

Application of RVVP power cord


RVVP is a type of cable with a soft conductor PVC insulated wire outer layer and PVC sheath. Copper core PVC insulated PVC sheathed soft cable, also known as electrical connection anti-interference soft cable. RVVP cables are suitable for efficient and safe transmission of data in communication, audio, broadcasting, audio systems, anti-theft alarm systems, intelligent automation systems, automatic meter reading systems, fire protection systems, and other areas that require anti-interference line connections. What kind of wire is rvvp The rated voltage of RVVP cable is 300/300V, and the commonly used number of cores is 2-24. The commonly used core wires include: 0.5 square, 0.75 square, 1.0 square, 1.5 square, 2.5 square, 4 square, 6 square, etc. RVVP cable is somewhat different from RVV cable. RVVP cable uses copper wire weaving, which has better electromagnetic compatibility characteristics. Therefore, it is particularly suitable for installation sites with harsh electromagnetic environments and small installation distances. RVVP cable products can be installed in cable trays and hoses for indoor installation. RVVP cables come in two types: flame retardant and fire-resistant: RVVP flame-retardant cables are not easily ignited and are used in situations with high requirements for flame retardant performance. RVVP fire-resistant cables can maintain a certain period of safe operation even under combustion conditions. They are used in situations where there are high requirements for cable fire resistance characteristics, and customers can choose different types of cables according to different requirements.
