Technical Parameters

Electrical properties

Among the relevant electrical parameters, the conductor DC resistance (20°C) must comply with the requirements of GB/T 3956 standard to ensure that its resistance performance meets the specification indicators.

In terms of insulation resistance (70°C), the standard value is ≥0.011MΩ・km. This value guarantees the insulation performance of the insulation material at a specific temperature and prevents problems such as leakage.

The power frequency withstand voltage test requires no breakdown at 3000V for 5 minutes, which is a strict test of the insulation strength and safety of electrical equipment.

For KVVP products, the standard shielding effect value is ≥60dB, which can effectively shield external electromagnetic interference and ensure the stability of signal transmission.

These parameter standards regulate the performance and safety of electrical products from different dimensions, jointly ensuring the quality and reliability of the products.

Mechanical properties

Tensile strength requirements:

≥12.5N/mm² (insulation)

Elongation at break requirements:

≥125% (insulation)

≥6D (unarmored)/≥12D (armored)

Environmental characteristics

Operating Temperature:

-15℃～+70℃

Short circuit temperature:

160℃（5s）

Flame retardant properties:

Pass GB/T 18380.3 (optional)

Product Features

Anti-interference design

Optional copper wire braided shield (KVVP) or aluminum foil shield to effectively suppress electromagnetic interference

Twisted pair design (such as DJYVP model) is suitable for signal transmission

Strong protection performance

Armored model (KVV22) compression resistance ≥ 4000N/100mm, suitable for direct burial

Waterproof type (KVVP2-22) passed IP67 test

Safe and reliable

Flame retardant type (ZR-KVV) passed the bundled combustion test

Low smoke zero halogen type (WDZ-KVV) meets the requirements of GB/T 19666

Easy to install

Flexible cable (KVVR) has a small bending radius and is suitable for complex paths

Color-coded cores for easy identification during installation

Application Scenarios

In factory automation control scenarios, it is recommended to use KVVP type cables, which have anti-electromagnetic interference properties and can effectively ensure stable signal transmission.

KVV type cable is suitable for building automation system, which is economical and practical, and can meet functional requirements while controlling costs.

Internal wiring of mechanical equipment, KVVR type cable has the advantage of good flexibility, which facilitates flexible wiring in a small space

In places like subways and tunnels where there are dense crowds and high fire safety requirements, the flame retardant and low smoke characteristics of WDZ-KVV22 cables can reduce smoke hazards in the event of an accident.

In the petrochemical environment, KYJV type cables can operate stably under complex and harsh working conditions due to their oil and corrosion resistance.

Selection Guide

Laying requirements

Bridge laying:

Filling rate <40%

Direct burial depth:

≥0.7m (need to lay sand and cover bricks)

Bending Radius:

≥6 times the cable diameter

Wiring requirements

Bridge laying:

Filling rate <40%

The shield layer needs to be grounded at one end

Multi-stranded flexible wires require crimping terminals

Precautions

Avoid laying cables parallel to power cables (spacing >0.3m), and lay cables of different voltage levels in separate slots.
