Hello everyone, selection of instrument cable models
Thread Content
Hello everyone, does anyone have information on selecting instrument cable models?
Occasionally found on Baidu; it seems okay, so I’m sharing it with you. Cable selection: The composition and order of cable models are as follows: 1: Category, purpose; 2: Conductor; 3: Insulation; 4: Inner shielding layer; 5: Structural characteristics; 6: Outer shielding layer or derivatives; 7: Usage characteristics. Items 1–5 and item 7 are represented by pinyin letters, while polymer materials are indicated by the first letter of their English name. Each item can consist of 1–2 letters； Item 6 is 1-3 digits. Principle of omission in model numbers: In wire and cable products, copper is the main conductor material; therefore, the code for a copper core is omitted, with the exception of bare wires and bare conductor products. For categories such as bare wires and bare conductors, power cables, and electromagnetic wire products, the category code is not indicated; wire and cable products for electrical equipment and communication cables are also not listed, but sub-category or series codes are provided instead. Item 7 refers to markings for various special usage scenarios or additional special requirements, indicated by pinyin letters after a “-”. Sometimes, to highlight that item, it is written at the very beginning. Such as ZR- (flame retardant), NH- (fire resistant), WDZ- (low smoke, halogen-free; enterprise standard), -TH (for humid and hot areas), FY- (termite resistant; enterprise standard), etc. Digital code: Armoring layer, Outer covering layer or sheath
0: None ---
1: Interlocked armoring, fiber outer covering
2: Double-layer steel tape, polyvinyl chloride outer sheath
3: Fine round steel wire, polyethylene outer sheath
4: Thick round steel wire
5: Rippled (corrugated) steel tape
6: Double aluminum (or aluminum alloy) tape
8: Copper wire braiding
9: Steel wire braiding
Meaning of cable model designation:
1. Purpose code – Unspecified means power cable; K denotes control cable, P denotes signal cable.
2. Insulation code – Z: oil-impregnated paper; X: rubber; V: polyvinyl chloride; YJ: cross-linked polyethylene.
3. Conductor material code – Unspecified means copper; L means aluminum.
4. Inner shielding layer code – Q: lead coating; L: aluminum coating; H: rubber sheath; V: polyvinyl chloride sheath.
5. Derived code – D: non-dripping; P: dry insulation.
6. Outer sheath code.
7. Special product code – TH: humid tropical area; TA: dry tropical area.
8. Rated voltage – in KV units.
Considerations for selecting cable models:
1. SYV: Solid polyethylene-insulated RF coaxial cable.
2. SYWV(Y): Physically foamed polyethylene-insulated cable for cable TV systems. Video (RF) coaxial cables (SYV, SYWV, SYFV) are suitable for closed-circuit surveillance and cable TV projects. SYWV(Y) and SYKV are cables dedicated to cable TV and broadband networks. Structure: (Coaxial cable) single oxygen-free round copper wire + physically foamed polyethylene (insulation) + (tin wire + aluminum) + polyvinyl chloride (polyethylene).
3. Signal control cables (RVV sheathed cables, RVVP shielded cables) are suitable for building intercom systems, security alarms, fire protection, automatic meter reading, and other applications. RVVP: Soft cable with copper core, polyvinyl chloride insulation, and polyvinyl chloride shielded sheath. Voltage: 300V/300V; 2–24 cores. Uses: Instruments, meters, intercom systems, surveillance, and control installations.
4. RG: Cable with physically foamed polyethylene insulation, used for transmitting digital and analog signals in hybrid coaxial-fiber networks (HFC).
5. KVVP: Braided shielded cable with polyvinyl chloride sheath. Uses: Signal transmission, control, and measurement in electrical appliances, instruments, and distribution devices.
6. RVV (227IEC52/53): Soft cable with polyvinyl chloride insulation. Uses: Household appliances, small power tools, instruments, and lighting fixtures.
7. AVVR: Soft cable with polyvinyl chloride sheath, used for installation purposes.
8. SBVV HYA: Data communication cable (for indoor and outdoor use), used for telephone communications, connecting radio equipment, and wiring in telephone distribution networks.
9. RV, RVP: Cables with polyvinyl chloride insulation.
10. RVS, RVB: Cables suitable for connecting household appliances, small power tools, instruments, meters, and lighting fixtures.
11. BV, BVR: Cables with polyvinyl chloride insulation, used for fixed wiring in electrical appliances, instruments, and lighting fixtures.
12. RIB: Speaker connection cables.
13. KVV: Control cable with polyvinyl chloride insulation. Uses: Signal transmission, control, and measurement in electrical appliances, instruments, and distribution devices.
14. SFTP: Twisted pair cable, used for transmitting telephone calls, data, and information over networks.
15. UL2464: Computer connection cable.
16. VGA: Monitor cable.
17. SYV: Coaxial cable used for transmitting RF signals in wireless communication, broadcasting, surveillance systems, and related electronic devices (including multi-purpose coaxial cables).
18. SDFAVP, SDFAVVP, SYFPY: Coaxial cables designed specifically for elevators.
19. JVPV, JVPVP, JVVP: Copper-core cables with polyvinyl chloride insulation and copper wire braiding, used for computer control applications
