Application Scene
YJV flame retardant cable is widely used in power stations, subways, tunnels, high-rise buildings, large-scale industrial and mining enterprises, oilfields, coal mines and other places, especially in the environment where cable laying is more intensive and outstanding. In addition, it is also suitable for the cable flame retardant, smoke density, toxicity index has special requirements of the place, such as subway, tunnel, nuclear power plants, etc.
Price information
The price of YJV flame retardant cables is usually higher than ordinary YJV cables. Different grades of flame retardant performance (A, B, C) also affect the price, in which ZA products have the highest price, followed by ZB and ZC products.
Frequently Asked Questions (FAQ):
I. Product Awareness
Q: What is the difference between YJV and flame retardant YJV?
A: YJV is a cross-linked polyethylene insulated PVC sheathed power cable, which does not have specialized flame retardant properties. Flame-retardant YJV is based on YJV, which has the ability to prevent or delay the occurrence or spread of flame by using flame-retardant materials for insulation, sheath, taping and filling, such as ZRA-YJV, ZRB-YJV, ZRC-YJV and so on.
Q: What is the meaning of ZA, ZB, ZC on flame retardant YJV cables?
A: This is the grade marking of flame retardant cable, ZA stands for flame retardant grade A, ZB stands for flame retardant grade B and ZC stands for flame retardant grade C. The flame retardant characteristics ZA＞ZB, ZRC-YJV, ZRB-YJV, etc. ZA＞ZB＞ZC, they are classified according to GB/T18380-2008 standard by controlling the volume of non-metallic materials contained in the specimen and the fire time.
II. Application Scene Category
Q: In which places are flame retardant YJV cables applicable?
A: It is suitable for indoor, tunnel and pipeline. It can be used for power transmission lines in buildings, factories, shopping malls, hospitals, schools and other places with high fire protection requirements, as well as power supply systems in some flammable environments, which can effectively reduce the risk of fire and ensure the safety of personnel and equipment.
Q: Compared with ordinary YJV cables, what special scenarios are flame retardant YJV cables more suitable for?
A: In crowded places, such as theaters and gymnasiums, once a fire breaks out, flame-retardant YJV cables can slow down the spread of the fire and buy time for people to evacuate. In places with a lot of flammable materials, such as oil depots, chemical warehouses, etc., ordinary YJV cables may cause a big fire, while flame retardant YJV cables can reduce this risk. In important power facilities, such as substations, the use of flame-retardant YJV cables can reduce fire damage to the power system and safeguard the power supply.
Installation and Maintenance
Q: Is the laying requirement of flame retardant YJV cable the same as that of ordinary YJV cable?
A: The basic laying requirements are similar, such as can be laid indoors, tunnels, pipelines and so on. The laying temperature should not be lower than 0℃, and should be pre-heated when it is lower than the minimum permissible temperature. No armor layer of the cable, the permissible bending radius should be not less than 6 times the outer diameter of the cable; armored or copper shielding structure of the cable, should be not less than 12 times the outer diameter of the cable. However, fire-retardant YJV cables may need to take additional fire blocking measures when passing through flammable areas or passing through fire separations such as walls and floor slabs.
Q: How do I perform routine maintenance on flame-retardant YJV cables?
A: Regularly check the appearance of the cable for damage, aging, cracking, etc., especially the insulation and sheath. Check the connecting parts of the cable to make sure that the connection is firm and there is no heat or fire. Regularly conduct electrical performance tests such as insulation resistance tests on the cables to ensure that their performance meets the requirements. Avoid long-term exposure of cables to high temperature, humidity and corrosive environment, and keep the cable laying environment clean and dry.
Fourth, the price and procurement category
Q: How much more expensive is flame retardant YJV cable than ordinary YJV cable?
A: Generally speaking, the price of flame retardant YJV cables is about 20%-50% higher than that of ordinary YJV cables, depending on the flame retardant grade, cable specifications and other factors. The higher the flame retardant grade, the more expensive the price, for example, the price of ZA product > the price of ZB product > the price of ZC product.
Q: What do I need to pay attention to when purchasing flame retardant YJV cables?
A: It is necessary to specify the required flame retardant grade, cable specifications, voltage level and other technical parameters to ensure that they are in line with the use of scenarios and design requirements. Choose qualified and reputable manufacturers, and check the quality test reports and certificates of the products. Sign a detailed procurement contract to clarify the product specifications, quantity, price, delivery time, quality standards and other terms, if necessary, you can ask the manufacturer to provide samples for inspection.
