Conduit plastic fittings refer to pipe connectors or accessories made of plastic materials, which are mainly used to connect, control or enhance the functions of plastic pipes.
Conduit plastic fittings work
The main role of Conduit plastic fittings is to protect the electrical wiring, provide the necessary support and connections, and ensure the safe and reliable operation of the electrical system.
1. Protect the electrical line is the basic function of Conduit plastic fittings. They protect the wire or cable from physical damage, such as being trampled, rubbed or exposed to harsh environments. Different types of conduit materials, such as PE or PVC, provide different levels of protection, ensuring that the wire is safe to use in all conditions .
2. Provide the necessary support and connection . Conduit fittings include couplings, elbows, connectors, etc. These fittings not only protect the wire, but also provide structural support through proper installation. They ensure that the wires are properly fixed and connected during the wiring process, avoiding loose or falling wires, thereby improving the stability of the entire electrical system .
3. Ensure the safe and reliable operation of the electrical system . In accordance with national electrical regulations (such as NEC) and local regulations, proper conduit installation and use is key to ensuring electrical safety. The use of appropriate conduits and accessories can prevent wire overheating, short circuit and other safety hazards, to ensure personal and property safety.
Types
The main types of conduit plastic fittings include couplings, elbows, connectors, set screws, compression fasteners and various adapters. These fittings are used to connect and fix conduits to ensure the safety and stability of electrical lines.
Couplings, elbows and connectors are common types of fittings used to adjust the direction and angle of conduits. Set screws and compression fasteners are used to fix conduits to structures such as walls or ceilings. In addition, adapters are used to connect different types of conduits to ensure the continuity and safety of electrical lines.
Laying methods
Underground laying
Underground laying, also known as buried laying, refers to the method of burying electrical conduits underground for laying. Its advantages are beautiful, safe, waterproof, and no ground space occupied. It is often used in areas with small sites and dense buildings. During the laying process, special attention should be paid to waterproof measures to avoid failures caused by water erosion.
Overhead laying
Overhead laying refers to the method of laying electrical conduits suspended in the air. It is generally suspended by overhead poles or hoisting equipment. Its advantages are easy installation and high reliability. It is suitable for areas with long distances such as crossing rivers and roads. However, it also has defects such as being easily affected by weather and easily damaged by foreign objects, and requires regular inspection and maintenance.
Trench laying
Trench laying refers to the method of laying electrical conduits buried in underground trenches. Generally, trenches need to be excavated and filled, and the trenches need to be protected and waterproofed. Its advantages are safety, beauty, and easy expansion. However, the construction process is relatively complicated and requires high skills of construction personnel.
