1, RVSP is an ordinary shielded copper-core polyvinyl chloride insulation stranded connection flexible wire. Used for those occasions where the transmitted signal requirements are very high, shielding external interference than the RVS series better than the effect, the cost is also higher than the RVS.
2, RVVSP is a copper core PVC insulated shielded PVC sheathed stranded flexible cable. It is suitable for semi-industrial and industrial environments, industrial and mining enterprises, medical buildings, when the transmission bandwidth is greater than 500MHz, or when it needs to support 2.5G/5G, 10GBASE-T and other places or when it needs to be highly shielded from interfering signals.

Wire and cable model naming
Overview
The complete naming of wire and cable is usually more complex, so people sometimes use a simple name (usually the name of a category) combined with the model specification to replace the complete name, such as "Low-voltage cable" stands for all plastic-insulated power cables of 0.6/1kV class. Wire and cable type spectrum is more complete, it can be said that, as long as the standard type specification of the wire and cable is written, you can clarify the specific product.
Wire and cable product naming has the following principles:
1, the content included in the product name
(1), the product application occasions or the name of the size of the class
(2), the product structure of the material or type;
(3), the product's important features or additional features.
Basically named in the above order, sometimes in order to emphasize the important or additional features, the features will be written in front of the front or the corresponding structure before the description.
2, the order of structure description
Product structure description from inside to outside according to the principle: conductor - & gt; insulation - & gt; inner protective layer - & gt; outer protective layer - & gt; armor type.
3, simplified
In the case of not causing confusion, some of the structure description of the omitted or abbreviated, such as automotive wire, soft wire in the aluminum conductor is not allowed, so do not describe the conductor material.
4, with the first letter of the Hanyu Pinyin capitalization of the insulation type, conductor materials, inner sheath materials and structural features. For example, Z represents paper (zhi); L represents aluminum (lv); Q represents lead (qian); F represents split-phase (fen); ZR represents flame retardant (zuran); NH represents fire-resistant (naihuo).
5, with numbers to indicate the composition of the outer armor layer, there are two digits. No number represents no armor layer, no outer being layer. The first digit represents the armor, the second digit represents the outer being, such as coarse steel wire armored fiber outer being expressed as 41.
6, the cable model according to the arrangement of the cable structure is generally sequential order: insulation materials; conductor materials; inner sheath; outer sheath.
7, cable products with the model number, rated voltage and specifications. The method is in the model and then add the description of the rated voltage, the number of cores and nominal cross-sectional area.
Two, list
RV, RVV, RVVP, RVVY, RVVYP, KVVRP, (N)2YSLC, ZR-RE, ZR-REE, ZR-REEP, PUR, LIYY, LIYCY, LIYY(TP), LIYCY(TP) , LI2YCY, PIMF, LIHH. LIHCH.
Three characteristics
CEF--Ethylene Propylene Rubber Insulated Neoprene Sheathed, Marine Flame Retardant Power Cable.
CVV--Polyvinyl chloride insulation, polyvinyl chloride sheath marine flame retardant power cables.
Oxygen tank wires are often used BV, BX, RV, RVV series wires BV - copper-core PVC-insulated wire, long-term permissible temperature of 65 ℃, the lowest temperature -15 ℃, the operating voltage of 500V AC, DC 1000V, fixed laying indoors and outdoors, can be open also can be concealed. BX - copper-core rubber-insulated wire. --Copper core rubber insulated wire, the maximum operating temperature of 65 ℃, laid indoors.
RV--Polyvinyl chloride insulated single-core flexible wire, maximum operating temperature 65 ℃, minimum operating temperature -15 ℃, operating voltage AC 250V, DC 500V, used as instruments and equipment for internal wiring. PVC insulated and sheathed flexible wire, allowing long-term operating temperature of 105 ℃, operating voltage AC 500V, DC 1000V, used for wet, high mechanical protection requirements, often moving and bending occasions.
Four, common models
VV said: PVC insulation (the first V), PVC sheathed (the second V) YJV22 said: crosslinked polyethylene insulation (YJ), PVC sheathed (V), steel armored (22) model plus "ZR" or "FR". "FR" for flame retardant cables (wires). Add "L" for aluminum wire.
Fifth, the type of wire is simpler:
BVV - PVC insulated and sheathed copper wire, BV - PVC insulated copper wire, BVR - PVC insulated copper wire, BVR - PVC insulated copper wire, BX - rubber-insulated copper wire, RHF - neoprene rubber-coated copper wire.
