U-PVC plastic porous power conduit optical fiber high voltage underground communication protection tube

Product Description

1. Product introduction

PVC-U porous pipe: PVC-U porous power cable protection pipe is made of hard polyvinyl chloride (PVC-U) as the masterbatch, adding anti-impact agent, stabilizer and other auxiliary materials through a unique mold to form a plum blossom or square nine-hole tube-shaped power communication pipe composed of nine square holes of the same size. It is also called plum blossom tube or grid tube.

The inner wall of this kind of pipe is smooth, and optical cables can be passed directly through it, which can save man-hours. Its structure is reasonable, its use value is high and its service life is long. It is mainly used in communication cable industries such as China Mobile, China Railway Communications, China Unicom, China Netcom, radio and television, and electric power. It implements the communications industry standard of the People's Republic of China: YD/T841.2-2016 standard. PVC grating pipe

It uses hard modified polyvinyl chloride as the main raw material, adds impact-resistant improvers, transfer agents and other preparations, and undergoes high-speed mixing and extrusion molding to achieve excellent properties such as pressure resistance, aging resistance and corrosion resistance. Its shape and structure are arc-shaped square corners and neatly arranged. Products include single hole, four holes and six holes.

Nine holes, etc., the grid tube is generally 6 meters per tube, and is connected by sockets. The tube and the sheathing tube are integrated without the need for secondary cable threading, and the one-time molding has high compressive strength.

2. Product features

1. Porous structure design

- Adopt single hole, 4 holes, 6 holes, nine holes or customized hole layout, and spacer rib design between holes to avoid cable cross interference.

- The inner walls of each hole are smooth and the cable threading resistance is small, which facilitates later maintenance and expansion.

2. Excellent physical properties

- High-strength compression resistance: ring stiffness ≥8kN/m² (can be upgraded according to needs), resistant to ground load and earth pressure.

- Strong corrosion resistance: Resistant to acid, alkali, salt spray and chemical substances, suitable for complex environments such as moisture and underground.

3. Safe and flame retardant

- Comply with YD/T841.2-2016 standard, the flame retardant grade reaches V-0 level, it self-extinguishes when removed from fire, reducing fire risk.

4. Convenient construction

- Light weight (density is about 1.5g/cm³), easy to transport and install; supports casing docking or socket connection, and has good sealing performance.

- Can be equipped with special elbows, tees and other accessories to meet the needs of curved laying.

5. Long life and environmental protection

- Excellent aging resistance, service life of more than 50 years, recyclable materials, and meets environmental protection requirements.

3. Application scenarios

- Direct underground burial or pipe gallery laying of power cables and communication optical cables

- Urban roads, highways, railways and other infrastructure facilities

- Construction of power pipeline networks in industrial parks, residential areas, airports and ports, etc.
