介紹：

一、變頻電纜主要用于變頻電源和變頻電機之間連接用的電纜，以及額定電壓0.6/1kV及以下的輸配電線路中，作傳輸電能用。變頻電纜尤其適用于冶金，紡織，金屬加工，造紙、礦山，鐵路和食品加工等行業(yè)。現(xiàn)我公司生產(chǎn)的普通型變頻電力電纜、耐高溫型變頻電力電纜、柔軟型變頻電力電纜和低煙無鹵型變頻電力電纜可滿足不同場合的使用。

1、 Variable frequency cables are mainly used for connecting cables between variable frequency power supplies and variable frequency motors, as well as for transmitting electrical energy in transmission and distribution lines with a rated voltage of 0.6/1kV and below. Variable frequency cables are particularly suitable for industries such as metallurgy, textiles, metal processing, papermaking, mining, railways, and food processing. The ordinary variable frequency power cables, high-temperature resistant variable frequency power cables, flexible variable frequency power cables, and low smoke halogen-free variable frequency power cables produced by our company can meet the needs of different occasions.

6 變頻電纜特點分析變頻調(diào)速技術(shù)關(guān)系到變頻電機、變頻電源和連接電纜，這段電纜長度并不很長，截面也不很大，絕緣性能屬于電力電纜范疇，因為實際的工作頻率為30～300 Hz，常簡稱為變頻電纜。變頻電纜作為電機與變頻控制器的電力傳輸載體，由于傳輸功率大、傳輸頻率變化時間短造就了它***的工作特點：1.脈沖電壓對絕緣的影響大；2.電纜本體對外發(fā)射電磁波；3.中性線電流的疊加。這就要求電纜具有1.抑制高次諧波電壓累加造成絕緣擊穿；2.抑制高次諧波電流累加造成中性線過載；3.抑制高頻電磁波對環(huán)境的污染三大問題。為了解決這三大問題就要求電纜具有1.對稱的結(jié)構(gòu)；2.良好的電磁屏蔽；3.增大中性線載流能力。一、由于需要對稱得電纜結(jié)構(gòu)，所以電纜芯數(shù)為3芯、3+1芯（其中一芯為同心導(dǎo)體結(jié)構(gòu)——T）、3+3芯（3大3小結(jié)構(gòu)）。二、由于需要良好的電磁屏蔽，所以該電纜須***金屬屏蔽。三、由于需要增大中性線載流能力，所以建議該電纜中心線截面大于等于一半主線芯截面，zui好等于主線芯截面。

Analysis of the characteristics of variable frequency cables: Variable frequency speed regulation technology is related to variable frequency motors, variable frequency power supplies, and connecting cables. This section of cable is not very long and has a small cross-section, and its insulation performance belongs to the category of power cables. Because the actual working frequency is 30-300 Hz, it is often referred to as variable frequency cables. As the power transmission carrier for motors and variable frequency controllers, variable frequency cables have the following working characteristics due to their high transmission power and short transmission frequency change time: 1. Pulse voltage has a significant impact on insulation; 2. The cable body emits electromagnetic waves externally; 3. The superposition of neutral current. This requires cables to have the ability to suppress insulation breakdown caused by the accumulation of high-order harmonic voltages; 2. Suppress the accumulation of high-order harmonic currents causing neutral line overload; 3. Suppress the three major issues of environmental pollution caused by high-frequency electromagnetic waves. To solve these three major problems, cables are required to have a symmetrical structure; 2. Good electromagnetic shielding; 3. Increase the current carrying capacity of the neutral line. 1、 Due to the need for a symmetrical cable structure, the number of cable cores is 3 cores, 3+1 cores (one of which is a concentric conductor structure - T), and 3+3 cores (3 large and 3 small structures). 2、 Due to the need for good electromagnetic shielding, this cable must be metal shielded. 3、 Due to the need to increase the current carrying capacity of the neutral line, it is recommended that the centerline cross-section of the cable be greater than or equal to half of the main core cross-section, preferably equal to the main core cross-section.

4、 AC voltage test: The voltage should be applied sequentially between each insulated conductor and the other conductors and the wrapped metal layer, with a test voltage of 3500V/5 minutes, and the insulation should be free of breakdown. The experiment should be conducted at ambient temperature.
