Brief introduction of 1 rubber insulated flexible cables and rubber insulated wires

1.1 INTRODUCTION

Rubber insulated flexible cable is suitable for AC rated voltage Uo/U of 450 / 750V and below power, household appliances and all kinds of mobile electrical equipment and tools.

Rubber insulated fixed wiring is suitable for electrical equipment and lighting fixtures such as AC rated voltage Uo/U 300/500V and below.

As an electrical insulating material, rubber has been used in the wire and cable industry for a long time. It has good elasticity, softness, water resistance, high mechanical properties and good electrical insulation properties, especially the rubber made of various synthetic rubbers developed in recent years. It has the characteristics of oil resistance and non delayed combustion, and is difficult to replace other materials. Cable insulation material is still widely used in low voltage, requiring frequent movement and soft occasion.

Our factory's rated voltage 450 / 750V and below rubber insulated flexible cables, 300/500V and below rubber insulated wires and flexible wires are designed and manufactured in accordance with People's Republic of China national standard GB5013.1 ~ 5013.7 - 2008 and machinery industry standard JB8435.1 - 8735.3 - 2011 and JB1601-93.

Technical characteristics of 1.2 rubber insulated flexible cables and rubber insulated wires

1.2.1 rated voltage

The rated voltage is the reference voltage for the cable (line) design and the electrical test. It is expressed in Uo/U, and the unit is V.

Uo is the voltage effective value between any insulated conductor and "ground" (surrounding medium). U is the voltage effective value between any two phase conductor of a multicore cable (line) or a single core cable (line) system.

In AC system, the rated voltage of cable (line) should be at least equal to the nominal voltage of the cable (line) system.

In DC system, the standard voltage of the system should not exceed 1.5 times the rated voltage of the cable.

If the rated voltage of the cable (line) is at least equal to the standard voltage of the system, the cable (line) can be used at a working voltage higher than 10% of the rated voltage.

1.3 usage characteristics

The long-term allowable working temperature of 1.3.1 rubber insulated flexible cable should not exceed 60 degree C.

The 1.3.2 "W" type cable has weatherproof and certain oil resistance. It is suitable for outdoor or oil contaminated applications.
