HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. ? 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.

　　生产的矿用通信电缆主要用途如下：型号名称规格用途MHYV（PUYV）聚乙烯绝缘阻燃聚氯乙烯护套矿用信号电缆2-57/0.28用于平巷、斜巷及机电硐室MHJYV（PUJYV）聚乙烯绝缘阻燃聚氯乙烯护套加强矿用通信电缆2-57/0.28（三钢四铜）用于平巷、斜巷、有较好的抗拉强度MHY。

RVV是铜芯聚氯乙烯绝缘聚氯乙烯护套软电缆.有绝缘,有护套,二芯及以上.RVS是铜芯聚氯乙烯绝缘对绞软线,只有绝缘层,没有护套,只有二芯规格.BVR电线是一种配电柜专用软电线，也叫二次线。采用铜芯聚氯乙烯的绝缘软电线,其应用于固定布线时要求柔软的场合。深受广大电工及建筑装饰人员喜欢。装修中水电改造都是隐蔽工程，暗铺的电线是不可以随意更换的，所以电线的选择直接关系到日后的用电安全。BV和BVR线的区别：材质相同，都是铜芯聚氯乙烯绝缘线，区别在于：BV线是较硬的单芯硬线，BVR是较软的多芯软线，相同面积的所承受的电流相同。

　　产品描述导体：实芯铜导体，直径0.5mm绝缘：实芯聚烯烃线对：四对，色谱为：蓝/蓝白、橙/橙白、绿/绿白、棕/棕白缆芯：四芯绞合护套：阻燃PVC或低烟无卤外径5.6mm特性阻抗：100Ω产品应用10/100BASE—T以太网（IEEE802.3）10/100BASE—Tforethernet（IEE。

BV line, BVR line, RVSP double stranded shielded cable, RVS double stranded cable, RVB parallel line, RV line RVSP Shielded twisted-pair cable RVSP (shielded twisted-pair cable, shielded cable, shielding twisted-pair electric (HYVP, RVVP) RVVP twisted-pair shielded cable < < shielded wire > > is shielded twisted-pair cable RVSP series on the basis of RVS coupled with a layer of copper wire shielding net, so the transmission loss, shielding the outside world better than RVS series, but because of the copper wire shielding network, its cost is also much higher than RVS series. Are often used to those who has a high re on the transmission. Technical indicators: polyvinyl chloride insulated cable long-term allowed working temperature over 70 ℃, the cable temperature under installation should not below 0 ℃, outer diameter (D) is less than 25 The allowable bending radius of mm cable shall not be less than 4 times the outer diameter of the cable. Diameter (D) of 25 mm and above of permissive bending radius of cable, not less than 6 times of cable diameter.
