RVVZ communication room flame retardant soft structure cable - RVVZ (also known as ZRVVR) series of flame retardant soft-tight cable is also a flame-retardant soft core power cable, which uses a multi-layer twisted filament composite twisted form, with good flexibility, It has high bending performance and high flame retardancy. It is suitable for the internal connection lines of telecommunication equipment distribution systems in telecommunication, post and telecommunications, railway, chemical, fire fighting, communications and chemical industries. It is suitable for both fixed and mobile cables. Especially useful in special circumstances.
Name: Communication equipment power cord (flame-retardant and fire-retardant flexible cable for communication power)
Specifications: 6-240mm
a DC Cable - A flame-retardant flexible cable for communication power is a flame-retardant flexible cable used in power transmission and distribution systems for communication bureaus (stations) and high-rise buildings.
b Flame-retardant flexible cables for telecommunication power supply are used for overhead, pipelines, indoor cable trenches, and direct buried underground.
Cable Standard: Enterprise Standard Product Model: ZA-RVV (ZRRVV, ZRVVR, RVVZ) Flame Retardant Flexible Cable for Communication Power Supply ZA-RVV22 (ZRRVV22, ZRVVR22, RVVZ22) Flame Retardant Steel Tape Armored Soft Cable for Communication Power Supply ZRYJVR, ZRYJVR22 Communication Flame-retardant flexible cable for power supply Flame-retardant flexible cable for communication power Flame-retardant performance Flexible power cable for communication power supply In the specified test conditions, the sample is burned. After the test fire source is removed, the flame spread is only within the limited range. Residual flame or residual self-extinguishing characteristics within a limited time.
Flame-retardant flexible cables for telecommunication power supply Rated voltage The rated voltage is the reference voltage for cable design and electrical performance tests.
The rated voltage is expressed by U0, U and the unit is V.
U0 - Voltage rms value between any insulated conductor and "ground" (metal sheath or surrounding medium of the cable).
U--Voltage rms between any two-phase conductors of a multi-core cable or single-core cable system,
When used in AC systems, the rated voltage of the cable should be at least equal to the nominal voltage of the cable system used. This condition applies to U0 and U values.
When used in a DC system, the nominal voltage of the system should not exceed 1.5 times the rated voltage of the cable.
Note: The operating voltage of the system allows long time to exceed 10% of the nominal voltage of the system. If the rated voltage of the cable is at least equal to the nominal voltage of the system, the cable can be used at an operating voltage greater than 10% of the rated voltage.
Fire-retardant flexible cable for communication power use Characteristics a, Flame-retardant flexible cable for communication power supply Rated operating voltage: 450/750V, 600/1000V.
b. Long-term operating temperature of flame-retardant flexible cable conductor for communication power supply: 70°C.
c. The ambient temperature of the communication power supply shall be not lower than 0°C when the flame retardant flexible cable is laid.
d. Minimum bending radius of flame-retardant flexible cable for communication power supply: non-armored cable: flame retardant type is 6 times the cable diameter, armored cable: 20 times the cable diameter
