Shielded Cable Model Specification Table Picture and Price Abstract: In the field of telecommunications and data transmission, shielded cables play a crucial role in ensuring reliable and high-quality signal transmission. This article will provide a detailed explanation of the shielded cable model specification table picture and price from four aspects: cable types, specifications, shielding materials, and pricing. 1. Cable Types Shielded cables come in various types to meet different application requirements. One common type is the twisted pair cable, which consists of two insulated copper wires twisted together to reduce electromagnetic interference (EMI). Another type is the coaxial cable, which has an inner conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer. Coaxial cables are widely used for video or RF signal transmission. The third type is the fiber optic cable with a metallic shielding layer. Fiber optic cables use light signals instead of electrical signals for data transmission and offer high bandwidth capabilities over long distances. Lastly, there are also hybrid cables that combine multiple types of conductors within one jacket to cater to specific needs. 2. Specifications The shielded cable model specification table provides detailed information about each cable's specifications such as conductor size (gauge), number of pairs or cores (for multi-pair or multi-core cables), insulation material (e.g., PVC or polyethylene), overall diameter, weight per unit length, etc. Conductor size determines the current-carrying capacity and resistance of the cable while insulation material ensures proper electrical isolation between conductors. The number of pairs/cores indicates how many separate circuits can be transmitted through one single jacket. 3. Shielding Materials To minimize EMI interference from external sources or prevent signal leakage from within the cable itself, shielding materials are applied to shielded cables' construction. Commonly used shielding materials include aluminum foil tape/braid shields that wrap around individual pairs/cores or overall shields that cover all conductors together. Aluminum foil tape provides excellent coverage against EMI but may not be as effective at low frequencies compared to braided shields made from tinned copper strands. Overall shields provide maximum protection but may add bulkiness to the final product. 4.Pricing Pricing for shielded cables varies depending on several factors such as length required by customers; higher quantities often result in lower unit prices due to economies-of-scale benefits during manufacturing processes; customizations like color-coding jackets might incur additional costs; Moreover,the choice between different types also affects pricing - fiber optic cables tend to be more expensive than twisted pair or coaxial ones due their advanced technology involved; Lastly,the quality level required can significantly impact pricing too- higher-quality materials usually come at higher costs but ensure better performance,reliability,and durability in demanding environments; In conclusion, the shielded cable model specification table picture provides valuable information about various aspects including different types available,cable specifications such as conductor size,numberofpairsorcores,andshieldingmaterialsused.Italsohelps customers understand how these factors influence pricing decisions when purchasing these essential components for their telecommunicationanddatatransmissionneeds.Withthegrowingdemandforreliableandspeedycommunicationsystems,it'simportanttochooseappropriateshieldedcableswiththe right specificationsandpricingtomeetthedesiredperformancestandardsandincreaseoverallnetworkefficiency
