Ⅰ. Introduction
As a leading cable supplier, Anyte Cable, CE NHXH cable offers you the best choice. We offer a variety of cable products to meet your every need. Our products include low voltage cables, high voltage cables and special cables. Our cable products are in line with national and international standards, and can provide professional technical support.
Ⅱ. What is CE NHXH cable
The CE NHXH of the cable means that XH is the highway cable standard, NH is the high-voltage cable standard, and CE is the EU safety certification mark. CE NHXH cables are suitable for use in high-voltage transmission and projects such as highways, railways, and waterways.
Ⅲ. Advantages of CE NHXH cables
1. Can significantly reduce power distribution costs
- Compared with the closed busway, the price is cheap, the project cost is reduced, the economic index is high, the comprehensive benefit is obvious, and the specifications are complete, flexible selection, and arbitrary combination.
- The branch head can arbitrarily set the branch position according to the needs of the distribution point of the power distribution system.
2. Low installation environment requirements and easy construction
- The building area is small, and there is no requirement for the space size of the civil construction.
- Simple laying, convenient installation, low requirements for the use environment, can be directly laid in cable trenches, special cable shafts of buildings, or in different cable trays, with low installation accuracy.
- Compared with the closed bus duct, the direction of the cable is random and the bending radius is small, which greatly reduces the difficulty of construction and reduces the space size.
- The installation labor intensity is small, the construction period is short, and it is only one tenth of the closed busway installation.
3. Excellent shock resistance, air tightness, water resistance and fire resistance
- It has excellent shock resistance. Generally, the closed mechanical connection busway is installed in parallel with the wall. When the wall is subjected to vibration, the joints of the closed busway are loosened, and the prefabricated branch cables will not be affected. Especially in No action is required to pass through the settlement joints of the building.
- Good airtightness and waterproofness, can operate normally in humid environment, and can also be laid in the open air and buried in the soil.
- The fire-resistant prefabricated branch cable keeps 90min normal power transmission operation under the condition of burning.
4. Maintenance free
- After the branch cable is installed according to the specified method, the one-time opening rate is high.
- The whole system of prefabricated branch cables in normal operation does not need any maintenance and maintenance in normal times.
- Easy emergency repair in the later stage and extremely low maintenance cost
Ⅳ. How to use CE NHXH cable
- First check whether the cable is damaged.
- Minimize cable bending when wiring.
- Insulated terminals or soldered terminals should be used for cable connection.
- Cable laying should avoid external force.
- In the process of laying, if there is a fault, it should be repaired in time.
- Pay attention to safety when using CE NHXH
- As power and control cable
- Machines and equipment that need to continue their function during a fire (emergency elevators, fire pumps, etc.).
- The ventilation system is connected to the fire alarm system.
- In emergency lighting of fire escape exits.
- Emergency power supply.
- Where it is necessary to protect human life and valuable materials and equipment.
Ⅴ. Characteristics of CE NHXH cables
- CE NHXH power cable has high pressure resistance, high tensile strength, good wear resistance, etc.
- Has excellent pressure resistance performance, can withstand high voltage output. In addition, it also has good tensile strength and can withstand large external forces.
- CE NHXH cable is suitable for use in various climatic conditions and has good abrasion resistance. Therefore, it can still maintain good working performance after long-term use.
- It should be noted that it has certain resistance to seawater, salt spray and chemical corrosive substances, but it cannot be used at high temperature.
Ⅵ. Precautions for CE NHXH Cables
CE NHXH power cable is made of polyethylene through a special process, which has excellent fire resistance, cold resistance, pressure resistance and chemical corrosion resistance. But the CE NHXH cable should pay attention to the following matters when installing and using it.
- The installation must comply with the requirements of the national standard GB50367-2002 “Electrical Installations in Buildings Part 2: Horizontal Wiring”.
- The CE NHXH cable should be stretched as much as possible during the laying process. If it has to be stretched, appropriate measures should be taken to reduce the stretch.
- The performance of the cable should be tested before the NHXH cable is laid, and the appropriate installation method and cable outer diameter should be selected according to the test situation.
- The cables should avoid friction and impact when laying.
- During the laying process of cables, avoid direct sunlight as much as possible, and take appropriate sun protection measures if necessary.
Ⅶ. Applications for CE NHXH cables
CE NHXH cables have been widely used in industrial, agricultural and other applications, and can effectively transmit various voltage signals. CE NHXH power cables have excellent voltage resistance and temperature resistance, and are suitable for use in high-voltage and high-temperature environments.
