RVV and KVV, RVVP and KVVP
Difference: The wire used in RVV and RVVP is a flexible wire composed of multiple strands of fine copper wire, namely RV wire.
The wires used in KVV and KVVP are hard wires composed of a single thick copper wire, that is, BV wires.
AVVR and RVVP
Difference: The same thing, but the name of the internal cross section less than 0.75 square millimeters is AVVR, and the name of greater than or equal to 0.75 square millimeters is RVVP.
SYV and SYWV
Difference: SYV is a video transmission line, insulated with polyethylene.
SYWV is a radio frequency transmission line with physical foam insulation used in cable TV.
RVS and RVV2 core
Difference: RVS is made of twisted twin-core RV wire without an outer sheath, and is used for broadcast connection.
RVV2 core wire is directly placed into a cable, with an outer sheath, used for power supply, control signal and other aspects.
Stainless steel fasteners of the Self-tapping series are a type of hardware used to join or secure materials together. These fasteners are specifically designed to create their own threads as they are driven into a pre-drilled hole, eliminating the need for a separate tapping process.
The stainless steel material used in these fasteners offers excellent corrosion resistance, making them suitable for outdoor or high-moisture environments. They are also known for their durability and strength, ensuring a secure and long-lasting connection.
These fasteners typically have a sharp, pointed end that allows them to penetrate and cut through the material as they are driven in. They may have a hexagonal or Phillips head for easy installation using a wrench or screwdriver.
The self-tapping feature of these fasteners allows for quick and efficient installation, saving time and effort. They are commonly used in construction, automotive, and manufacturing industries, as well as for various DIY projects.
Overall, stainless steel fasteners of the Self-tapping series are reliable, corrosion-resistant, and convenient to use, making them a popular choice for a wide range of applications.
