Rubber cable is the use of rubber as the insulation material of the cable, which can withstand a higher load, in the power system, machinery, steel, and other fields widely used. If you want to know more about the characteristics, uses, and considerations of flexible rubber cables, or you are currently struggling to choose rubber wire, this article will answer these questions.

EN 50525-2-21 IEC 60245-4 STANDARD 300/500V 450/750V H05RN-F H07RN-F RUBBER CABLE

Rubber cable features

From the name, we can understand that typical rubber cables are made of various rubber materials as protective covers for cables. Early rubber materials used natural rubber, but there has been large-scale use of a variety of synthetic rubber, including styrene-butadiene rubber, ethylene propylene rubber, butyl rubber, etc., to increase the oil resistance, cold resistance, heat resistance, and other characteristics, improve the performance of the cable. Rubber is a thermosetting plastic elastomer that reaches an elastomer after being vulcanized or cross-linked and will not melt when reheated. At low temperatures, it will not become hard and cannot be stretched out. Rubber cable grommets prevent cables and pipes from being damaged by the external environment and ensure the normal operation of devices.

Type of Rubber Cable

In different use scenarios, rubber wire has different classifications. The welding machine needs the core to be very soft, insulated, and flame retardant and may come into contact with acids, alkalis, oils, and other substances during use, and needs to have the characteristics of wear-resistant cream. The cable on the submersible pump mostly uses 450/750V AC voltage and also needs to be waterproof cables. In more extreme mines, rubber cables are also required to withstand corrosion and frequent bending, dragging, and impact, which requires a thicker rubber wire protection layer.

ZMS cable provides H07RN-F heavy-duty rubber cable for greater flexibility and flexibility while having a tougher jacket for use on-site, in mines, agricultural appliances, or other small appliances. The H07RN-F cable is available in two specifications (300/500v, 450/750v), supports a maximum operating temperature of 65 ° C and a minimum operating temperature of -10 ° C, and guarantees a maximum conductor temperature below 160 ° C. In the laying process to ensure that the ambient temperature is not lower than -10℃. At the same time, it has a bending radius of no more than 10D.

H05V-K and H07V-K rubber cables are two different types of cable, H05V-K can withstand 300/500V voltage, and H07V-K can withstand higher voltage 450/750V. The cable structure is relatively simple, with five types of flexible copper as conductor, external insulation material, and cover using rubber. It can be used in the interior of lamps, closed pipes, cable pipes, or internal links of equipment switches, relays, instrument equipment panels, etc.

Use of Rubber Cable

Waterproof cables can prevent water from entering the cable and causing a dangerous short circuit. Waterproof rubber cable Waterproof structure and waterproof materials effectively increase the waterproof and moisture resistance of the cable. Underwater motors, submersible pumps, and others that need to work underwater or in a wet environment can use flexible rubber cable, rubber material is a kind of insulation material and is waterproof, effectively ensuring the cable’s electrical performance. The pump cable can also be specially selected, which can generally be used for the power transmission of the motor below 500V, and has excellent water resistance and softness to ensure the power transmission and electrical signal transmission inside the pump motor.

Mobile universal rubber cable suitable for general household appliances, power tools, and mechanical equipment. Light mobile rubber wire voltage is generally 220V, used in daily electrical equipment. Industrial electrical equipment usually uses medium or heavy-moving rubber cover wires. YQ light has excellent flexibility and generally does not bear additional external forces. The YZ medium has sufficient flexibility and can withstand normal mechanical forces. YC heavy duty can withstand a greater external force, its sheath has enough elasticity and mechanical strength, and there is a certain flexibility to ensure bending.

If you need to connect the welding machine to the tool, you can choose a rubber welding cable, which can carry a high current. Generally made of a multi-strand copper core plus rubber insulating material, it has good heat resistance and oil resistance. When in use, the appropriate section size should be selected according to the size of the current to ensure that the insulation layer will not be burned due to overheating.

Matters Needing Attention

Rubber cable has the advantages of soft, flexible, acid resistance, oil resistance, and high and low-temperature resistance, but poor wear resistance, weak tear resistance, and easy oxidation, but the price is higher. In contrast, PVC cables are not resistant to high temperatures and are easy to soften in high-temperature environments, increasing the risk. Therefore, PVC cable is generally used in cable laying, and its oxidation resistance is better than rubber wire.

Before using the rubber cable, it is necessary to pay attention to its rated voltage, rated current, and other related parameters to avoid safety hazards caused by overload use. Avoid contact with high-temperature equipment during installation, minimize telecommunication connectors, and install protectors.

How to Choose

Many rubber cables on the market make you dazzled, so firstly, you must analyze your needs and narrow the product range according to demand. For example, what kind of business these cables are used for, how many orders are ordered, and other special needs. After determining the product, it is necessary to screen the cable supplier to ensure that they can provide perfect service, you can go to the official website or forum to check the previous customer’s evaluation of them, which is very helpful for you. An experienced supplier can not only provide high-quality products and favorable prices but also provide advice on the analysis of your needs.
