Although BVV hard cable and BVVB cable are only one letter difference, the inherent difference is very obvious. Both have their own characteristics in terms of structural shape, application scope and usage characteristics. In the following, I will explain the differences between the two in detail.

First of all, BVV cable, all known as copper core PVC insulated PVC sheathed hard wire, is also commonly known as hard sheathed wire. The BVVB cable, known as copper core polyethylene insulating layer polyethylene sheath flat type cable, is a common type specification in the sheath cable. Bushing cable refers to a single or multi-core cable containing bushing layer, one of which is a white polyethylene bushing, and the interior is wrapped with two BV cables. This type of line is usually a copper core power line, in addition to a layer of cable jacket outside the power line, the power line also has a protective layer outside. BVVB cable insulation layer material and bushing material are polyethylene, according to the different performance, the product can be divided into insulation layer, flame retardant, fire protection three types, different types have different application scenarios.

First, the appearance of the difference BVV hard cable is round, the interior is directly composed of wire sleeve and electrical conductor, the color is red, yellow, yellow green, blue, green, black and so on. The BVVB cable is flat, and several BV lines are wrapped inside the jacket, with a double layer of protection, and the color is only white.

BVV hard cable is suitable for AC current 450/750V and below power systems, household appliances, but also can be used in open wire. The BVVB cable is suitable for rated voltage 300/500V, requiring a flame retardant place welders, instrument panels, communication products, power systems and lighting lines fixed laying.

Three, the characteristics of different BVV hard cable for copper core polyvinyl chloride insulation polyvinyl chloride sheathed wire and cable, with acid and alkali resistance, oil resistance, moisture, anti-aging and other advantages. The allowable working temperature of the cable for a long time shall not exceed 65 ° C, the temperature of the cable conductor shall not exceed 160 ° C when the short circuit occurs (the duration shall not exceed 5 seconds), and the ambient temperature when laying the cable shall not be lower than 0 ° C.

BVVB cable is copper core polyvinyl chloride insulated polyvinyl chloride flat wire and cable, the long-term allowable working temperature of the cable should not exceed 70℃, the cable laying temperature should not be lower than 0℃, the rated voltage is 300/500V. In addition, it can also be customized according to requirements (anti-aging, wear resistance, low temperature resistance, waterproof, chemical corrosion resistance, environmental protection, low smoke halogen free, etc.) BVV cable.

The above is a detailed introduction to the difference between BVV hard cable and BVVB cable, and I hope it will be helpful to you.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
