The importance of sealing measures for cable shafts

Take preventive measures, avoid and reduce fire hazards, and prevent greater economic losses and fire accidents with less economic means; Fireproof and flame-retardant protection measures and technical treatment should be taken for the sealing of cable shafts to achieve multiple prevention effects such as fire prevention, dust prevention, and preventing short circuits and corrosion caused by small animals from burning; Reasonably set up fire prevention treatment areas to protect cables and equipment, and provide convenience for operators. The sealing of cable shafts is very important for ensuring the safe operation of the power system. The main reasons are as follows: 1. Preventing foreign objects from entering the shaft can prevent garbage, small animals, and other foreign objects from entering the shaft, and prevent cable insulation from being damaged or causing short circuits. 2. Isolating fire hazards and sealing the well can block the source of fire, prevent the rapid spread of fire through the shaft, and protect the safety of cables. 3. A well sealed structure to prevent illegal excavation of vertical shafts from stealing current can prevent it. 4. Keeping the well sealed can avoid water accumulation in the well, maintain a relatively closed environment, and facilitate cable heat dissipation. 5. A good sealing method for preventing pests and rodents can prevent moths and rodents from biting the cable insulation layer. 6. Ensure that the cable repair space is sealed and isolated, and the cable laying in the well is more orderly, which is conducive to cable fault detection and repair.

The significance of using electrical polymer moisture-proof sealing agent

Due to the fact that cable branch boxes are mostly distributed in urban green belts, the planned roads and industrial parks of the new city have been operating in humid, dirty, and high-temperature environments for a long time. Due to the installation process, the cable terminals in the branch box cable warehouse may experience short circuit faults due to wet grounding. Below is the significance of using electrical polymer moisture-proof sealing agents.

How effective is the polymer moisture-proof sealing agent

Electrical equipment has a wide range of applications. If the relative humidity reaches 80%, electrical equipment will have various side effects, affecting the normal use of electrical equipment and playing a good auxiliary role in industrial production. However, moisture is one of the important factors causing damage to electrical equipment, so moisture prevention of electrical equipment is a very important task. Polymer moisture-proof sealing agents are particularly important. Let's learn about the effectiveness of polymer moisture-proof sealing agents.

Construction technology of polymer moisture-proof sealing agent

In humid environments, indoor power facilities are increasingly facing various threats, which have a significant impact on the operation of electrical equipment. In electrical engineering, when the relative humidity is greater than 80% RH, it is called high humidity. High humidity is the main factor for electrical equipment accidents, and polymer moisture-proof sealing agents are particularly important. Below, let's learn about the construction process of polymer moisture-proof sealing agents.

How to do waterproof sealing for cables and wires in the distribution room when entering the house

At present, embedding steel pipes in the wall at the entrance of cables is a common method of cable waterproofing and sealing. When laying cables, large cross-section cables can be individually threaded through a single steel pipe. Waterproofing and sealing of cables is relatively simple and easy, and the effect of waterproofing and sealing can meet the design requirements. However, a few or even dozens of small cross-section cables can be threaded into their own steel pipe, The sealing between cables and their development has become a quite thorny issue, often leading to water seepage or leakage. Once the rainwater in the cable trench is not drained smoothly, the rainwater system will flow back along the cable trench, which is easily caused by the transformation and distribution room

Construction Method of Sealing Leakage for Cable Waterproof Sealing

Research experiments have shown that the faults of medium and low voltage power cables in buildings are mostly caused by faults in the intermediate joints and terminal heads of the cables, as well as poor sealing and moisture infiltration, resulting in a decrease in insulation strength. However, the medium and low voltage power cable network mostly adopts a tree shaped power supply method, with a large number of cable terminal heads. In response to this situation, the cable waterproof sealing method is adopted for the sealing of structural damage points with small seepage areas.
