Insulated flame retardant MPP pipes, suitable products for laying urban and rural power lines

Insulated flame retardant MPP pipe is a special protective pipe for power lines made of modified polypropylene as the main raw material and processed by extrusion molding and performance optimization. It is a suitable product developed for urban and rural power line laying scenarios. Under the premise of retaining the basic mechanical properties of ordinary MPP pipes, it focuses on strengthening the insulation and flame retardant properties, which can meet the safety protection needs of power pipelines under different working conditions. It is a commonly used pipe category for power line protection projects.

The core practical advantages of this product mainly include four points:

The first is that the insulation flame retardant performance meets the standards. The insulation resistance of the pipe meets the requirements of the relevant national standards for power protection pipes, which can effectively avoid the risk of pipeline leakage and external conductive medium interference, and avoid problems such as short circuit and signal interference during power operation. The flame retardant grade meets the requirements of the corresponding standards. It is not flammable in case of open fire and extinguishes immediately after leaving the fire, which can reduce the risk of fire spread caused by line failure and improve the safety of power pipeline operation.

The second is stable weathering and damage resistance. The pipe can withstand long-term use temperatures from -5 ° C to 70 ° C, adapt to the climate environment of most regions in China, and has the properties of acid and alkali corrosion resistance and external pressure impact resistance. Whether it is buried laying or bridge erection, it can resist soil corrosion, heavy object rolling, daily weathering and other losses. Under normal use conditions, the service life can reach decades, reducing the cost of later operation and maintenance replacement.

The third is strong construction adaptability. The pipe has a light weight and can be connected by a variety of connection methods such as hot melt docking and socket connection. The interface has good sealing performance and is not prone to leakage problems. The pipe can be moderately bent according to the construction needs without a lot of cutting and splicing, which can reduce the construction difficulty under complex terrain, shorten the operation period of power line laying, and reduce the construction cost investment.

Fourth, the efficiency of the threading operation is high. The inner wall of the pipe is smooth without burrs and bumps, and the friction coefficient is low. It will not scratch the outer skin of the cable when passing the power cable, which can reduce the threading resistance, improve the efficiency of the wiring operation, and also reduce the risk of outer skin wear during the long-term use of the cable. Extend the service life of the cable.

The product is suitable for a wide range of scenarios, including the buried laying of power lines in urban and rural power grids, pipeline protection for the transformation of power grids in old cities, power pipeline network construction in industrial parks, the erection of supporting power lines along transportation lines, and power ground entry projects in residential areas. It can also be adapted to the isolation and protection needs of power cables and communication cables laid in the same trench. Suitable groups include power engineering contractors, urban and rural pipeline network construction authorities, municipal engineering construction parties, infrastructure procurement departments of real estate development units, and power operation and maintenance units.

At present, the production and testing of this type of pipe strictly follow the relevant national standards for power pipe protection products. Before leaving the factory, it needs to pass the full inspection of insulation performance, flame retardancy, compressive performance and other indicators. After meeting the requirements, it can be listed and circulated. It can fully meet the compliance procurement and construction requirements of various urban and rural power line laying projects.
