Advantages and principles of PVC row trunking in preventing leakage
Publish Time: 2024-11-18
PVC row trunking has significant advantages in preventing leakage, which is mainly due to its own material properties and structural design principles.
From a material perspective, PVC (polyvinyl chloride) is an excellent electrical insulating material. Its molecular structure determines that there are almost no freely movable charge carriers inside it. Under normal circumstances, PVC has an extremely high resistance value, which makes it difficult for current to pass through it. When the insulation layer of the wires in the cable trough is damaged, which may cause leakage, PVC row trunking can effectively prevent the current from leaking to the outside of the cable trough, thereby ensuring the safety of surrounding personnel and equipment.
In terms of structural design, PVC row trunking generally has good sealing. The trough body and the cover of the cable trough are tightly matched, reducing the existence of gaps. This design can prevent external impurities such as water vapor and dust from entering the interior of the cable trough, avoiding leakage caused by the degradation of the insulation performance of the wires due to these factors. At the same time, the tight structure can also prevent the wires in the cable trough from rubbing against the cable trough wall due to accidental movement, further protecting the integrity of the insulation layer of the wires.
In addition, PVC row trunking usually undergoes strict quality inspections during the production process to ensure the purity of its materials and overall uniformity. High-quality PVC materials will not be partially conductive due to aging, deformation and other problems during use. Moreover, some high-quality PVC row trunking will also add special additives to enhance its insulation performance and stability, so that it can always maintain good anti-leakage ability during long-term use.
In practical applications, whether in a humid industrial environment or an ordinary indoor environment, PVC row trunking can provide reliable protection for electrical wiring systems with its excellent anti-leakage advantages. It can effectively avoid electric shock accidents, short-circuit failures and other problems caused by leakage, ensure the stable operation of the power system, and make people safer and more assured when using power equipment.
