Rubber-sheathed cables are flexible and movable types of electrical cables that consist of multiple fine copper strands as the conductor, surrounded by rubber insulation and an outer rubber sheath. These cables come in various forms, including general-purpose rubber-sheathed flexible cables, welding cables, submersible motor cables, radio equipment cables, and photographic lighting cables. They are widely used in different electrical applications such as power cords for household appliances, industrial machinery, and electrical equipment. These cables can be used both indoors and outdoors, depending on the environmental conditions.
Depending on the mechanical stress they are subjected to, rubber-sheathed cables are categorized into three types: light, medium, and heavy. Each type has a specific cross-sectional design suited for different purposes. Light-duty rubber cables are typically used in everyday appliances and small electric devices, where flexibility, light weight, and good bending performance are essential. Medium-duty cables are commonly found in industrial and agricultural settings, while heavy-duty cables are used in demanding environments like port machinery, high-intensity searchlights, and large-scale irrigation systems.
Waterproof rubber cables and submersible pump cables are specifically designed for use with submersible motors. They are capable of operating under water for extended periods, offering excellent electrical insulation even under high pressure. These cables are also known for their durability and ability to withstand frequent movement without damage.
For radio equipment, two types of rubber-sheathed cables are available—shielded and unshielded—both of which meet the necessary requirements for signal transmission. In the field of photography, modern photographic cables have been developed with compact designs and improved performance, making them ideal for both indoor and outdoor use. They are gradually replacing older, less heat-resistant models.
In addition to the standard categories, rubber-sheathed cables also include specialized types such as welding machine cables, which are designed for use in electric welding applications. These cables are suitable for connecting welding torches and grounding electrodes, with a rated voltage not exceeding 200V AC or 400V pulsating DC. They feature a single-core structure made from multiple flexible copper strands, wrapped in heat-resistant insulation and protected by a durable rubber outer layer.
Waterproof rubber-sheathed flexible cables are engineered to transmit power to submersible motors operating at voltages up to 500V. They maintain excellent electrical insulation properties even when submerged in water for long periods and can handle repeated bending without compromising performance. Their versatility and reliability make them a preferred choice in many industrial and marine applications.
Aluminum casement window is a common type of window in our daily life, which is diverse in design and function, and is widely used in office buildings, residential buildings, commercial buildings and other fields. Its opening mode is divided into internal opening and external opening two kinds. The inward opening means that the window sash opens in the indoor direction, while the open means that the window sash opens in the outdoor direction. The advantages of aluminum casement window: 1. Good ventilation performance: The opening Angle of casement window is large, which can effectively promote air circulation, especially in summer, and can effectively improve indoor air quality. 2. High safety performance: Due to the outward opening of the window sash, the risk of children falling from the window sill is reduced. At the same time, high-quality hardware accessories can provide better anti-theft protection. 3. Thermal insulation: The use of double or three layers of insulating glass casement window, can effectively block the outside cold and hot air, keep the indoor temperature stable, to achieve good thermal insulation effect. 4. Sound insulation effect is good: high-quality casement window adopts multi-layer sealing strip design, which can effectively isolate external noise and provide a quiet and comfortable environment for occupants. In short, casement Windows are a good choice because of their excellent ventilation, safety, sound insulation and a variety of material and design options!
