Difference Between Power Cord RVV And Rvvb

Rvvb is a kind of flat power cord with flexible structure. In fact, it is no different from RVV power cord. Some are only different in appearance. RVV power cord is round, while rvvb is flat power cord.

In rvvb power line, R indicates flexible cable, soft structure, and V refers to insulating layer polyethylene. The second V refers to polyethylene insulating sheath, and B refers to flat and flat. That is to say, the rvvb power cord is a flat sheath power cord. Rvvb generally only requires 2-core sheathed wires, while RVV cable models range from 2-24 cores.

In fact, the rvvb sheath power cord and RVV sheath power cord are power cords with the same main purpose, which are common switching power cables. The main difference is that the RVV power cord is round in appearance.

Rvvb and RVV power lines are all made of stranded multi-core copper wires. In the sales market, RVV is generally extruded power lines, which are extruded with extruded die shells. The internal gap is immediately filled with PVC. Generally, it has compact structure, shiny appearance and is not easy to be damaged. The skin is strong and has good compressive strength and compressive capacity.

The thickness of the protective wire sleeve of the section of rvvb is not as thick as that of RVV power line, and the tensile and compressive capacity are not as good as that of RVV power line. When selecting rvvb protective wire sleeve, pay more attention to whether the cable structure is symmetrical, which is not easy to cause cable cracking and cracking.

More importantly, only when the thickness of the ultra-thin part reaches a certain standard value can the compressive strength of the insulating layer be ensured, and the potential safety risk will not be caused by the small thickness of a certain point.

RVV power line and rvvb power line are used for supervision, home decoration, small and medium-sized special tools for household appliances in engineering projects. Rvvb power line saves indoor space compared with RVV power line to a certain extent.

When selecting the power line, it is proposed to use oxygen free copper power line with low resistor and very good transmission effect.
