High voltage cable manufacturers: take a look at the performance of the usual use of cable
Release time:
2023-02-18
High voltage cable manufacturers: take a look at the performance of the usual use of cable Refers to the new product's temperature resistance rating, operating temperature power transmission wire and cable heating and thermal conductivity characteristics, cable current capacity, short-circuit fault and load capacity, composite material thermal expansion and high temperature impact level, thermal deformation of raw materials and its prepreg or coating material drip characteristics.
High voltage cable manufacturers: take a look at the performance of the usual use of cable
1. Electrical performance
Conductivity-most of the goods provide better conductivity, some goods provide a certain range of resistors.
Insulation performance --- grounding resistance, electrode index, dielectric loss, electrical resistance characteristics, etc.
Transmission characteristics-refers to high-frequency transmission characteristics, anti-interference characteristics, etc.
2. Physical properties
Refers to compressive strength, elongation, bending, elasticity, flexibility, vibration resistance, abrasion resistance and mechanical impact resistance.
3. Thermal performance
Refers to the new product's temperature resistance rating, operating temperature power transmission wire and cable heating and thermal conductivity characteristics, cable current capacity, short-circuit fault and load capacity, composite material thermal expansion and high temperature impact level, thermal deformation of raw materials and its prepreg or coating material drip characteristics.
4. Corrosion resistance and weather resistance
Refers to electrochemical corrosion resistance, microbial and bacterial corrosion resistance, chemical (oil, acid, alkali, chemical agent, etc.) corrosion resistance, salt spray resistance, light resistance, low temperature resistance, mildew removal and its waterproof characteristics.
5. Aging characteristics
The level at which commodities and constituent raw materials maintain their original characteristics under the action of mechanical stress, electrical stress, internal stress and various other additional elements, or under the action of external natural conditions.
6. Other Features
It contains some of the characteristics of plastics (such as the strength of metal composites, stress relaxation, and the compatibility of fiber materials) and some of the special application characteristics of new products (such as undelayed combustion, resistance to molecular radiation sources, anti-moth bite, delayed transmission, and its kinetic energy damping, etc.).
The key to the technical performance of new products is based on the use of each major commodity, the scope of application, and the relationship between its supporting facilities, weapons and equipment. Among the various technical properties of a product, some are bound to be the main ones, which play a definite role and should be strictly managed. Some are genera. Sometimes some elements are also interdependent. It is therefore essential to carry out the exploration and analysis of comprehensive consideration.
High voltage cable manufacturers: cable assembly need to pay attention to matters
1, mine cable and heating pipeline parallel surface installation to maintain 2m spacing, cross to maintain 0.5m.
2. The distance of 0.5m is always maintained when the cable is assembled in parallel with other pipelines or in cross.
3. In the direct buried installation of cables, the buried depth of 1-35kV cables shall not be less than 0.7m.
4. In the installation of parallel surfaces of cables below 10kV, the spacing between them shall not be less than 0.1m,10-35kV shall not be less than 0.25m, and the crossing time spacing shall not be less than 0.5m.
The small bending radius of the cable, the multi-core cable cannot be lower than 15D, and the single-core cable cannot be lower than 20D(D is the cable diameter).
6. 6kv or above cable connector.
High voltage cable manufacturer: our company has all kinds of cables, welcome to call for advice.
