The cable is divided into high voltage or low voltage cable. If it is high voltage, there will be a layer of resin-like filler inside, which is used for insulation. In high voltage cable, this layer is the most important part of insulation. There is no such thing in the low pressure. Then there will be something like a ribbon in the inside. This is to fix each core of the cable and fill the gap in the middle.
As for the shielding layer, the power cable and the control cable are commonly used, as follows:
The role of the shield of the power cable is:
1. Because the current through the power cable is relatively large, a magnetic field is generated around the current. In order not to affect other components, the shielding layer can shield the electromagnetic field in the cable.
2. It can play a certain role of grounding protection. If the cable core is damaged, the leaked current can flow through the shielded laminar flow such as the grounding net to play a role of safety protection.
If it is a control cable, there is no difference. It is only in many places, especially the control cable of the computer system. The shielding layer here is used to shield the external influence, because its current is very weak, and it is very afraid of the external electromagnetic field.
Xintai Cable focuses on national standard products. The power cables and shielded control cables are sold at home and abroad.

The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
