When installing RVV elevator shaft cables, the following points should be noted:
1. Purchase wires: Choose RVV cables suitable for use in elevator shafts, and ensure that the quality meets national standards.
2. Material preparation: Before installation, relevant materials need to be prepared, including trapezoidal wire ducts, crimping terminals, electrical tape, screws, nuts, etc.
Installation of 3 cable trays: Cut the cable trays according to the required length and width, and fix them on the elevator shaft wall with screws and nuts.
4. Cable laying: In the elevator shaft, cable laying should follow the principle of "burying along the edge", ensuring that the height of the cable from the ground is more than 300mm and the distance from the shaft wall is more than 100mm. The bending radius of the cable should not be less than 5 times the diameter of the cable to prevent damage caused by excessive bending of the cable. The cable suspension must be firm and reliable, without loosening or shaking.
5. Environmental impact of installation: Choose a dry, ventilated, and environmentally clean place for installation.
Products application
The cable is suitable for dry rooms and various kinds of electric installation in industrial use enviornment. The cable as flexible control and connecting cable(cross section area is 0.5mm² or above)is specially suitable for the place of machine tool manufacturing, complete equipment installation engineering, power station, and the installation of heating and air-conditions. For the special flexibility, it is also used for the installation and fixation of elevator well hole(not as elevator travelling cable).
Products properties
Due to its good mechanical properties, excellent electrical insulation performance, and good chemical stability, polyvinyl chloride has a certain degree of electrical insulation performance. Excellent product performance and safe use.
The EKF20400 series adds a large cross-section (2.0 ²) yellow green grounding wire structure on the basis of the EKF20300, which is also suitable for elevator systems.

FAQ
Q1: What is the main purpose of fixing installation cables for RVV elevator shafts?
A1: RVV elevator shaft fixed installation cables are mainly used for fixed installation inside elevator shafts, for control, accompanying wiring, power supply, communication, monitoring, signal transmission, etc.
Q2: What are the requirements for the installation environment of RVV elevator shaft fixed installation cables?
A2: The installation environment should be selected in a dry, ventilated, and clean environment. Avoid exposing cables to extreme temperatures, humidity, or corrosive environments to ensure their stability and safety.
Q3: What is the minimum bending radius for fixed installation cables in RVV elevator shafts?
A3: The minimum bending radius depends on the specific specification and model of the cable. Generally speaking, the minimum bending radius for mobile installation is 15 times the outer diameter of the cable, and for fixed installation it is 6 times the outer diameter of the cable.
Q4: What are the characteristics of RVV elevator shaft fixed installation cables?
A4: The RVV elevator shaft fixed installation cable has excellent oil resistance, cold resistance, moisture resistance, and excellent wear resistance. It can withstand large mechanical stress and suspension force, and has good comprehensive performance when traveling.
Q5: Can RVV elevator shaft fixed installation cables be used for other occasions?
A5: In addition to the fixed installation of elevator shafts, RVV cables can also be used in other situations that require control and connection of flexible wires, such as mechanical manufacturing, complete equipment installation engineering, power plants, heating and air conditioning installation, etc. However, it should be noted that its special thin insulation overall flexible design is more suitable for the installation and fixed laying of elevator shafts, and is not suitable for use as elevator accompanying cables.
