Shanghai Daoqin Plastics Co., Ltd.

market upper cable tube/pipe is from types type to 配置都 has very more, in 选购 时候该 how to according to demand selection combined electrical cable? selection electrical cable not only need it applications, quality, price, Model/Grade is in 选购 时候 need focus/key point issues, lower 面东莞鼎誉 is large detailed 列出几点 electrical cable requirements, for large in 选购 时候 has 帮助.

一, combined standards requirements electrical cable product features

首先, has "CCC" certification 标识. electrical cable product due to and large 消费者 生 active has 密切 关系, it quality excellent poor, safety and 否直接 effect/influence large 消费者 人身 and safety. therefore, electrical cable product is strong/high made safety certification product, has production enterprise must China electrical product certification 委员会 certification "CCC" certification, obtain "CCC" certification 标志, in combined or product upper has "CCC" certification 标志. this category of enterprise product is large in electrical cable 时首先考虑.

二, electrical cable Model/Grade

selection combined electrical cable Model/Grade, is ensure safety use electrical front 提. selection electrical cable Model/Grade, need applications, conditions and electrical can safety scope/range and other. selection electrical cable specifications need 考虑考虑发 hot, electrical pressure loss 失, electrical density, machine strong/high degree and other conditions.  

according to experience, low pressure force its negative electrical relatively large, generally 先按发 hot conditions selection 截面, rear its electrical pressure loss and machine strong/high degree; low pressure lighting its for electrical pressure water requirements relatively high, can 先按允许 electrical pressure loss conditions selection 截面, again 验算发 hot conditions and machine strong/high degree; for high pressure 线路, 则先按经济 electrical density selection 截面, rear its hot conditions and electrical pressure loss 失; high pressure 架空线路, also 应验算 its machine strong/high degree.

四, electrical cable quality

currently market upper poor electrical 线都存 in decrease material issues. 1, long degree 不够; 2, wire drawing （即 electrical 线两头 coarse, in fine ）; 3, 导体材质不达标, electrical retardant combined standards requirements. most heavy is copper aluminum 导体, is aluminum filament 镀 一层 copper, make appearance 看起 跟 copper filament 一样, 但实际 upper copper electrical 线 载流 amount aluminum electrical 线一样. 4, insulation 材质达不 to standards requirements.
