介绍：

YVFR 是一种适用于油污、低温及频繁移动场合的特种电力软电缆，主要用于起重、冶金、港口等设备作为移动动力连接线。

YVFR is a special type of flexible power cable designed for oily, low-temperature, and frequent-motion environments, mainly used in cranes, metallurgy, ports, and similar equipment as mobile power supply lines.

结构组成

Structure & Construction

导体：多股细铜丝束绞，柔软性好，适合反复弯曲和移动使用。
Conductor: Stranded fine copper wires with high flexibility, suitable for repeated bending and mobile applications.
绝缘层：丁腈橡胶包裹，提供电绝缘和耐油性能。
Insulation: Nitrile rubber (NBR) insulation providing electrical insulation and oil resistance.
护套层：外层丁腈橡胶护套，增强耐磨、耐油和耐候能力。
Sheath: Outer NBR jacket enhancing abrasion, oil, and weather resistance.

常见派生型号包括：

Common variants include:

YVFRP：带铜丝编织屏蔽层，适用于有电磁干扰的环境；
YVFRP: With copper braided shielding, suitable for environments with electromagnetic interference (EMI);
YVFRB：扁形结构，适合空间受限或拖链安装；
YVFRB: Flat structure, suitable for space-limited installations or cable chains;
ZR-YVFR：阻燃型，用于防火要求较高的场合。
ZR-YVFR: Flame-retardant type for fire-safety-critical applications.

主要特点

Key Features

耐油性强：能够长期接触机油、润滑油、柴油等而不发生明显老化，适合油污严重的工业现场。
Excellent Oil Resistance: Withstands prolonged exposure to engine oil, lubricants, diesel, etc., without significant aging—ideal for heavily oil-contaminated industrial sites.
耐寒柔软：在较低温度下仍能保持柔韧性，不易变硬或开裂，适合寒冷地区户外或冷库使用。
Cold-Resistant Flexibility: Remains flexible at low temperatures without hardening or cracking, suitable for outdoor use in cold regions or cold storage facilities.
抗机械疲劳：可承受频繁弯曲、卷绕和拖拽，适合起重机卷筒、移动设备等动态敷设场景。
Mechanical Fatigue Resistance: Withstands frequent bending, reeling, and towing, suitable for dynamic installations such as crane drums and mobile machinery.
耐高温性能：在长期较高温度环境下仍能保持稳定的电气性能和物理性能。
High Temperature Resistance: Maintains stable electrical and physical properties under long-term high-temperature conditions.

应用领域

Application Fields

起重运输设备：如行车、龙门吊、港口岸桥的卷筒供电电缆。
Lifting & Transport Equipment: Such as overhead cranes, gantry cranes, and port quay crane drum cables.
重型机械设备：冶金轧机、焦炉机械、矿山堆取料机等移动设备。
Heavy Machinery: Mobile equipment including metallurgical rolling mills, coke oven machines, and mining stacker-reclaimers.
特种车辆：电动平车、大型工程车辆的随行供电线路。
Special Vehicles: Power supply lines for electric transfer carts and large construction vehicles.
恶劣环境场所：船舶甲板、石油平台、低温冷库等需要耐油耐寒的场景。
Harsh Environments: Decks of ships, oil platforms, cold storage warehouses, and other scenarios requiring oil and cold resistance.

选型与使用要点

Selection & Installation Guidelines

选型建议：
Selection Suggestions:

存在较强电磁干扰时，优先选择带屏蔽层的 YVFRP；
In strong EMI environments, prioritize YVFRP with shielding;
安装在拖链或空间狭窄位置，可考虑扁形结构的 YVFRB。
For cable chains or narrow spaces, consider the flat-structured YVFRB.

敷设注意：安装环境温度不宜低于 -25℃，避免在低温状态下强行弯曲造成护套或绝缘损伤。
Installation Note: Ambient temperature should not be lower than -25°C during installation; avoid forced bending at low temperatures to prevent sheath or insulation damage.
标识识别：正规产品外护套上一般连续喷印有型号、电压等级及生产厂家等信息。
Identification: Genuine products usually feature continuous inkjet printing on the outer sheath indicating model, voltage rating, and manufacturer information.
