Product Structure

Kyjv Control Cable 450750v

KYJV Control Cable 450/750V is mainly composed of a T1R copper conductor , PVC insulation and PVC sheath.

Conductor: Copper conductor , round standed or Shaped, Class 1,Class 2 to GB/T 3956, IEC 60228

Insulation: Insulation thickness, XLPE material property shall be as per GB/T 9330.

Core Colour: 2 cores: blue, brown or black

3 cores: green/yellow, blue, brown or blue, black, brown

4 cores: green/yellow, blue, black, brown or blue, black, brown, grey

5 cores: green/yellow, blue, black, brown, grey or blue, black, brown, grey, black

Above 5 coes: black cores with white number or white cores with black number

Outer sheath: Sheath thickness, PVC material property shall be as per GB/T 9330.

Flame-retradant cable: Flame-retardant PVC outer sheath material shall be used. The flame retardant grades can be classified into three categories: Bunch A, B, and C.

Fire-resistance cable: Two layer of Mica tape shall be wound around the conductor.

Performance parameter

The rated voltage is set at 450/750 V. Regarding the test voltage, the power frequency test voltage needs to reach 3 kV and be maintained for 5 minutes, ensuring no breakdown occurs during this process. The maximum operating temperature of the conductor is 70 ºC, while in the event of a short circuit, the temperature can rise to +160 ºC. In terms of conductor resistance, it strictly complies with the requirements for Type 1, Type 2, and Type 5 copper conductors specified in the GB/T 3956-2008 standard.

The flame retardant properties can be flexibly adjusted according to customer needs, meeting the requirements for bundled Class A, Class B, and Class C, respectively. The testing method follows the IEC 60332 or GB/T 18380 standards. The fire resistance is also excellent, capable of sustaining combustion in a 750ºC flame for 90 minutes without experiencing short circuits or disconnections. The testing method conforms to the IEC 60331 or GB/T 19216 standards.

Comparison between KYJV control cable and KVV control cable

Serial number	feature	KYJV control cable	KVV control cable
1	insulating material	cross-linked polyethylene（XLPE）	polyvinyl chloride（PVC）
2	sheath material	polyvinyl chloride（PVC）	polyvinyl chloride（PVC）
3	Long-term operating temperature	Up to 90°C	Up to 70℃
4	heat resistance	Good heat resistance, strong overload capacity, short-term overload temperature Up to approximately 250°C	The heat resistance is average, and overload can easily accelerate insulation aging. The short-term overload temperature can reach around 160℃
5	Insulation electrical performance	High insulation resistance, low dielectric loss, and good aging resistance	The insulation performance meets conventional control requirements, slightly inferior to XLPE
6	mechanical properties	High mechanical strength, good crack resistance, and strong anti-aging capability	It has good flexibility, but it tends to become hard and brittle under long-term high-temperature conditions
7	Applicable ambient temperature	Laying ambient temperature: 0℃~90℃	Laying ambient temperature: 0+℃~70℃
8	Core strengths	High temperature resistance, reliable insulation, long service life, suitable for complex working conditions	Good flexibility, low cost, stable flame retardancy, suitable for conventional scenarios
9	Applicable scenarios	1. Industrial high-temperature environments (such as near metallurgical facilities, power plants, and boiler rooms) 2. Control circuits that operate continuously for long periods and have a high likelihood of overload 3. Outdoor, humid, or locations with large temperature differences (such as municipal engineering projects and mines) 4. Automated control systems, such as PLC/DCS systems, that require high signal stability	1. Conventional control within building structures (such as lighting control, elevator auxiliary circuits) 2. Control circuits for indoor dry, normal temperature environments (such as wiring inside electrical distribution cabinets) 3. Applications that are cost-sensitive and do not require high temperatures (such as ordinary factory assembly lines)
10	cost	The materials and craftsmanship are slightly more complex, and the price is slightly higher than that of KVV	The production process is mature, offering high cost-effectiveness and even lower prices
