介紹：

YVFR 是一種適用于油污、低溫及頻繁移動(dòng)場(chǎng)合的特種電力軟電纜，主要用于起重、冶金、港口等設(shè)備作為移動(dòng)動(dòng)力連接線。

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.

結(jié)構(gòu)組成

Structure & Construction

導(dǎo)體：多股細(xì)銅絲束絞，柔軟性好，適合反復(fù)彎曲和移動(dòng)使用。
Conductor: Stranded fine copper wires with high flexibility, suitable for repeated bending and mobile applications.
絕緣層：丁腈橡膠包裹，提供電絕緣和耐油性能。
Insulation: Nitrile rubber (NBR) insulation providing electrical insulation and oil resistance.
護(hù)套層：外層丁腈橡膠護(hù)套，增強(qiáng)耐磨、耐油和耐候能力。
Sheath: Outer NBR jacket enhancing abrasion, oil, and weather resistance.

常見派生型號(hào)包括：

Common variants include:

YVFRP：帶銅絲編織屏蔽層，適用于有電磁干擾的環(huán)境；
YVFRP: With copper braided shielding, suitable for environments with electromagnetic interference (EMI);
YVFRB：扁形結(jié)構(gòu)，適合空間受限或拖鏈安裝；
YVFRB: Flat structure, suitable for space-limited installations or cable chains;
ZR-YVFR：阻燃型，用于防火要求較高的場(chǎng)合。
ZR-YVFR: Flame-retardant type for fire-safety-critical applications.

主要特點(diǎn)

Key Features

耐油性強(qiáng)：能夠長(zhǎng)期接觸機(jī)油、潤(rùn)滑油、柴油等而不發(fā)生明顯老化，適合油污嚴(yán)重的工業(yè)現(xiàn)場(chǎng)。
Excellent Oil Resistance: Withstands prolonged exposure to engine oil, lubricants, diesel, etc., without significant aging—ideal for heavily oil-contaminated industrial sites.
耐寒柔軟：在較低溫度下仍能保持柔韌性，不易變硬或開裂，適合寒冷地區(qū)戶外或冷庫(kù)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.
抗機(jī)械疲勞：可承受頻繁彎曲、卷繞和拖拽，適合起重機(jī)卷筒、移動(dòng)設(shè)備等動(dòng)態(tài)敷設(shè)場(chǎng)景。
Mechanical Fatigue Resistance: Withstands frequent bending, reeling, and towing, suitable for dynamic installations such as crane drums and mobile machinery.
耐高溫性能：在長(zhǎng)期較高溫度環(huán)境下仍能保持穩(wěn)定的電氣性能和物理性能。
High Temperature Resistance: Maintains stable electrical and physical properties under long-term high-temperature conditions.

特種車輛：電動(dòng)平車、大型工程車輛的隨行供電線路。
Special Vehicles: Power supply lines for electric transfer carts and large construction vehicles.
惡劣環(huán)境場(chǎng)所：船舶甲板、石油平臺(tái)、低溫冷庫(kù)等需要耐油耐寒的場(chǎng)景。
Harsh Environments: Decks of ships, oil platforms, cold storage warehouses, and other scenarios requiring oil and cold resistance.

選型與使用要點(diǎn)

Selection & Installation Guidelines

選型建議：
Selection Suggestions:

存在較強(qiáng)電磁干擾時(shí)，優(yōu)先選擇帶屏蔽層的 YVFRP；
In strong EMI environments, prioritize YVFRP with shielding;
安裝在拖鏈或空間狹窄位置，可考慮扁形結(jié)構(gòu)的 YVFRB。
For cable chains or narrow spaces, consider the flat-structured YVFRB.

敷設(shè)注意：安裝環(huán)境溫度不宜低于 -25℃，避免在低溫狀態(tài)下強(qiáng)行彎曲造成護(hù)套或絕緣損傷。
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.
標(biāo)識(shí)識(shí)別：正規(guī)產(chǎn)品外護(hù)套上一般連續(xù)噴印有型號(hào)、電壓等級(jí)及生產(chǎn)廠家等信息。
Identification: Genuine products usually feature continuous inkjet printing on the outer sheath indicating model, voltage rating, and manufacturer information.
