PVC Electrical Bushing Product Introduction

As an unknown hero hidden in the buildings, PVC electrical bushings are the last line of defense to protect us from the threat of electrical fires. However, there are various electrical bushings on the market. As consumers, how do we choose a good electrical bushing?

Performance characteristics of PVC electrical bushings Among the indicators required by the standard, such as: compressive performance, bending performance, electrical performance, and flame retardancy are important indicators of the performance of electrical tubing and this is also the evaluation of the quality of electrical bushings Important indicators. The advantages of our company's electrical bushings in these indicators are described below:

 Compression resistance:

It is to ensure that electrical bushings will not be crushed during the use, especially when buried concrete is buried. The national standard requirements are: Df ≤ 25% when the load is 1 minute, Df ≤ 10% . Our company's test index is: when the load is held for 1 minute, the maximum Df is 5%; the maximum value of Df is 1% when the load is unloaded for 1min.

Bending performance: 

The purpose is to test the cold bending performance of electrical bushings. The company's electrical pipe is -15, that is, the pipe is bent to 180 degrees without breaking under the condition of -15 ° C ± 2 ° C; The company's electrical bushing has no damage to the spring and the casing after the test There are no visible cracks on the surface of the sample, which is better than the national standard.

Electrical performance: 

It is used to test the insulation strength and insulation resistance of the pipe. When the electrical pipe produced by the company is charged with water for voltage test, a voltage of 2000V is applied and it is kept from being broken for more than 15 minutes. The insulation resistance of 100MΩ meets and exceeds the national standard requirements.

Flame retardant performance: 

If the electrical pipe is ignited, there should be no obvious flame propagation. After the fire source is removed, the casing flame should be extinguished within 30s (that is, the self-extinguishing time te≤30s). The self-extinguishing time of the pipes produced by the company can be controlled within 5 seconds. The oxygen index (determines the minimum oxygen concentration when the plastic just maintains stable combustion, expressed as the volume percentage of the oxygen content in the mixed gas), the national standard requires 32% or more, and the electrical pipes produced by the company can reach over 40%.

Advantages of Xinrong's PVC electrical bushings

1. The electrical pipes produced by the company are environmentally friendly. The stabilizers are formulated with organotin like other PVC pipes and will not cause pollution to the surrounding environment such as soil and rivers in the future. This is also the company the product is one of the important factors in the quality of the market.

2. The company's products such as double wall corrugated pipe extrusion machine have a high degree of automation from raw material mixing to extrusion, reducing human factors and ensuring excellent and stable quality; and mass-produced pipes in strict accordance with national standards. There are no grades for products, there is only one standard, and "sample tubes" are never produced. Over the years, no inconsistencies have occurred.

3. The company's electrical pipe uses TS vent and the pipe can be directly connected to the pipe, which greatly reduces the use of pipe fittings and saves user costs. Our PVC pipe extrusion line price is reasonable as well.

4. The company's management performance is ahead of its peers. The company can achieve the same quality products with the lowest cost and selling price and the highest cost performance.
