Ningde Mining Communication Cable Models and Specifications

This paper introduces the models and specifications of Ningde Mining Communication Cable, which are divided into two series: MVQ series and MGY series. The MVQ series includes MVQ2602, MVQ2604, MVQ2606, MVQ2608, and MVQ2610, while the MGY series includes MGY2602, MGY2604, MGY2606, MGY2608, and MGY2610. These cables are suitable for different communication systems in mines such as telephone, video, data transmission, etc. The specifications include the number of conductors, the cross-section area of conductors, the type of conductor material, the number of screens, the type of screen material, and the outer sheath material. These specifications ensure that the cables have good electrical performance, mechanical performance, and thermal performance to meet the requirements of mine communication systems.

I. Introduction

Ningde, a city in Fujian Province, China, is an important mining region. The mining industry in Ningde requires reliable and efficient communication cables to ensure safe and effective operation. This article provides an overview of the various models and specifications of mining communication cables used in Ningde.

II. Cable Models

In Ningde, several models of mining communication cables are commonly used. These models are selected based on the specific needs of the mining operation, such as the environment in which the cables will be used, the distance between communication points, and the required level of protection against electromagnetic interference (EMI). Common models include:

1、MVQ Series - This series of cables is designed for use in mines with high electromagnetic interference. The MVQ series provides excellent EMI protection and is suitable for applications where other cables may be subject to electromagnetic interference.

2、MYQ Series - This series is designed for use in mines with low electromagnetic interference. The MYQ series offers good mechanical protection and is suitable for applications where cables need to withstand heavy mechanical stress.

3、MYP Series - This series is a mineral-insulated, metal-sheathed cable designed for use in mines with high temperatures. The MYP series can withstand high temperatures up to 250 degrees Celsius and is suitable for applications where other cables may be subject to thermal degradation.

III. Cable Specifications

In addition to the models, the specifications of mining communication cables used in Ningde also vary based on the specific needs of the mining operation. Common specifications include:

1、Conductors - The conductors of these cables are made from copper or aluminum, with a diameter ranging from 0.5 to 4 millimeters (mm). The number of conductors also varies based on the capacity and distance requirements of the communication system.

2、Insulation - The insulation material used in these cables is typically a mineral-based compound that provides excellent thermal and electrical insulation properties. The thickness of the insulation layer varies based on the level of protection required against electromagnetic interference and mechanical damage.

3、Sheath - The sheath material used in these cables is either metal or plastic, providing mechanical protection and EMI shielding. The thickness of the sheath varies based on the level of protection required against mechanical damage and electromagnetic interference.

4、Length and Diameter - The length and diameter of these cables vary based on the specific needs of the mining operation. Lengths can range from several meters to several kilometers, while diameters can range from 10 to 50 millimeters (mm).

IV. Conclusion

In conclusion, the models and specifications of mining communication cables used in Ningde vary based on the specific needs of the mining operation. Selecting the right model and specification is essential to ensure reliable and efficient communication between various points within the mine, while also protecting against electromagnetic interference and mechanical damage.
