Application of related products in power systems

In the power system, reliable cable connections and protection are crucial for ensuring the stable transmission of electricity, the safe operation of equipment, and the safety of personnel. Products such as Plastic Cable Glands, Brass Cable Glands, Stainless Steel Cable Glands, Bellows Connectors and Fittings, and Blocking Parts each play an indispensable role in different links and scenarios of the power system with their unique performance characteristics.

I. Applications of Plastic Cable Glands in the Power System
(A) Applications in the Low-Voltage Distribution Network
Plastic cable glands are widely used in the cable laying of the low-voltage distribution network. They have good insulation properties, which can effectively prevent leakage between the cable and the external environment, ensuring the safety of residential and commercial electricity use. For example, at the cable connection points of distribution boxes and cable branch boxes in urban residential areas, plastic cable glands can provide reliable sealing and insulation protection. Even in humid environments, they can prevent moisture from penetrating into the cable, avoiding power outages caused by short circuits and ensuring the stability of the power supply.
(B) Applications in Indoor Power Wiring
Plastic cable glands also perform excellently in indoor power wiring projects. Due to their relatively lightweight materials and convenient installation, they can adapt to various complex indoor wiring environments. For example, in electrical shafts and cable trays inside buildings, plastic cable glands can flexibly seal the cables, preventing foreign objects such as dust and small animals from entering the cable passages, reducing the risk of cable failures caused by external factors and ensuring the normal operation of the indoor electrical system.

II. Applications of Brass Cable Glands in the Power System
(A) Applications in Power Switchgear
Brass cable glands play an important role in power switchgear. Their good electrical conductivity and mechanical strength enable them to operate stably in the high-current and high-voltage environment of the switchgear. At the cable inlet and outlet of the switchgear, brass cable glands can tightly fix the cables while ensuring good electrical connections, effectively reducing contact resistance, reducing heat generation, improving the efficiency of power transmission, and being able to withstand the mechanical stresses generated during the operation of the switchgear, preventing the cables from loosening or falling off and ensuring the reliable operation of the switchgear.
(B) Applications in Cable Connections in Substations
In the cable connection环节 of substations, brass cable glands are also one of the commonly used components. The cables in substations carry the transmission of high-voltage electrical energy, and the performance requirements for connection components are extremely high. The corrosion resistance and electrical conductivity of brass cable glands can meet this requirement. They can be used for a long time in harsh outdoor environments, resisting the erosion of wind and rain, while ensuring the efficient transmission of electrical energy between the cables and the equipment, providing strong support for the stable operation of the substations.

III. Applications of Stainless Steel Cable Glands in thePower System
(A) Applications in Power Facilities in Coastal Areas and High-Corrosion Environments
For power facilities in coastal areas or in the presence of highly corrosive media, stainless steel cable glands are the ideal choice. For example, in the power systems of wind farms by the sea, offshore oil drilling platforms, etc., stainless steel cable glands,凭借其卓越的耐腐蚀性, can effectively resist the erosion of seawater, salt spray, and chemical pollutants. In these extreme environments, they can maintain good sealing and mechanical properties for a long time, ensuring the reliability of cable connections and greatly reducing the risk of power failures caused by corrosion, ensuring the long-term stable operation of power facilities.
(B) Applications in High-Temperature and High-Pressure Power Pipes
In some high-temperature and high-pressure power pipe systems, stainless steel cable glands also play an irreplaceable role. For example, at the cable connection points near the steam pipes and high-temperature oil pipes in thermal power plants, stainless steel cable glands can withstand the thermal stresses in high-temperature environments and the pressure impacts in high-pressure environments. Their high-temperature and high-pressure resistant characteristics ensure the safety protection of the cables under harsh working conditions, preventing the cables from being damaged due to pipe leakage or excessive temperature, thus ensuring the continuity and safety of the entire power production process.

IV. Applications of Bellows Connectors and Fittings in the Power System
(A) Applications in Cable Line Compensation
In power cable lines, factors such as temperature changes and foundation settlement will cause the cables to expand and contract. Bellows connectors and fittings can adapt well to such changes. Their unique bellows structure can freely expand and contract within a certain range, effectively compensating for the length changes of the cables, avoiding damage to the insulation layer or cable breakage caused by excessive stretching or compression of the cables. For example, in long-distance transmission cable lines, especially those passing through areas with different geological conditions, bellows connectors and fittings can ensure that the cables can maintain good electrical and mechanical properties under the influence of various environmental factors, ensuring the stable transmission of electricity.
(B) Applications in Power Equipment Connections
In the connections between power equipment, bellows connectors and fittings also play an important role. They can provide flexible connection methods, facilitating the installation and debugging of equipment. For example, in the cable connections between transformers and distribution cabinets, or the transition connections between different specifications of cables, bellows connectors and fittings can achieve precise connection matching through their diverse joint forms and angle selections, reducing power loss and safety hazards caused by improper connections and improving the overall operating efficiency of the power system.

V. Applications of Blocking Parts in the Power System
(A) Applications in Cable Hole Sealing
During the cable laying process in the power system, holes will be left when the cables pass through walls, floors, etc. Blocking parts can be used to seal these holes. They can effectively prevent fire, smoke, water, and small animals from passing through the holes into the cable passages, avoiding damage to the cables or causing safety accidents. For example, in the cable shafts of buildings, after using blocking parts to seal the cable holes, a relatively closed cable running environment can be formed, improving the safety and reliability of the cable system and reducing the incidence of power failures caused by external factors.
(B) Applications in Cable Branch Box Protection
In cable branch boxes, blocking parts also have important application values. They can seal the idle cable interfaces, ventilation holes, etc. inside the branch boxes, preventing dust, moisture, and other impurities from entering the box, protecting the electrical equipment and cable joints inside the box. At the same time, in the event of a fire or other emergency situations, blocking parts can also play a certain role in flame retardancy and smoke prevention, buying time for power repair and personnel evacuation and reducing the loss of accidents.
In conclusion, products such as Plastic Cable Glands, Brass Cable Glands, Stainless Steel Cable Glands, Bellows Connectors and Fittings, and Blocking Parts each undertake unique functions in the power system. They cooperate and work together to jointly provide a solid guarantee for the safe, stable, and efficient operation of the power system and are an indispensable part of power engineering construction and maintenance
