Abstract

Disclosed is a PVC in-conduit arc-partitioned flame-retardant and insulated electrical conduit, comprising an outer wall of a flame-retardant and insulated electrical conduit (1) and a partition layer of a flame-retardant and insulated electrical conduit (2), characterised in that both of the outer wall of the flame-retardant and insulated electrical conduit (1) and the partition layer of the flame-retardant and insulated electrical conduit (2) are of the same PVC material; the partition layer of the flame-retardant and insulated electrical conduit (2), together with the outer wall of the flame-retardant and insulated electrical conduit (1), fixedly partitions the region in the conduit by means of integrated extrusion moulding; and the partition layer of the flame-retardant and insulated electrical conduit (2) is designed as an arc-shaped structure. This structure can effectively avoid the phenomenon of winding or knotting during the threading of cables, and effectively specify the path for threading cables, so that threading cables will not influence each other and are independent from each other, thereby realizing the effects of protecting cables and facilitating maintenance.

Description

一种PVC管内弧形分隔阻燃绝缘电工套管Flame-insulated insulated electrical casing with curved arc in PVC pipe 所属技术领域Technical field
本实用新型涉及一种在电工布线中明确区分布线走向的电工套管，尤其是能规范电工布线的线缆数量和避免线缆缠绕造成无法正常抽拉替换线缆的问题。The utility model relates to an electrician sleeve which clearly distinguishes the direction of the wiring in the electrician wiring, in particular, the problem that the number of the electrician wiring can be standardized and the cable winding can be prevented from being unable to pull the replacement cable normally.
背景技术Background technique
目前，公知的电工套管，都是管内壁不分区，电工布线只将线缆直接置于套管内直接穿线，当有2股线缆缠绕或者打结，在暗埋的电工套管内将很难直接抽取换线，而且在实际直接穿线布线中，电工布线若不按国家标准线(综合布线国家标准：GBT/T 50311-2007)暗敷直线管道的管径利用率应为50％～60％，弯管道应为40％～50％的标准穿线，过多根线缆穿线或线缆的横截面积大于线管内壁面积的40％，当遇到线缆漏电或损坏需更换线缆时，由于布线的线缆过于拥挤，将无法从暗埋的线管内直接抽取线缆换线，造成换线困难，而需重新开槽换线，将造成装修损失。At present, the well-known electrical bushings are not partitioned inside the pipe wall. The electrician wiring only directly places the cable directly into the casing. When two strands of cable are wound or knotted, it will be difficult in the buried electrical bushing. Directly change the line, and in the actual direct threading, if the electrical wiring is not in accordance with the national standard line (integrated wiring national standard: GBT/T 50311-2007), the diameter of the straight pipe should be 50% to 60%. The curved pipe should be 40% to 50% of the standard threading. The cross-sectional area of the excessive cable threading or cable is greater than 40% of the inner wall area of the line pipe. When the cable is leaked or damaged, the cable needs to be replaced. Because the cable of the wiring is too crowded, it is impossible to directly extract the cable from the buried pipe, which makes the wire change difficult, and needs to be re-grooved to change the line, which will cause decoration loss.
发明内容Summary of the invention
为了克服现有的布线不规范操作，直接从源头上预防布线管径利用率低于40％而造成后期暗敷线管内换线维护难的问题。本实用新型提供一种新型电工套管，该套管直接在管内壁分区，采用圆弧形分隔层分区，规定每个分区的线缆走向和管径利用率，从而方便地区分线路，避免线缆的缠绕或打结，使得每处线缆接头处均需要设置线盒接线装置，保证线路安全和维护方便。In order to overcome the existing irregular wiring operation, the problem that the wiring pipe diameter utilization rate is less than 40% is directly prevented from the source, which causes difficulty in maintenance of the wire change in the dark wire. The utility model provides a novel electrician bushing, which is directly partitioned on the inner wall of the pipe, adopts a circular arc-shaped partition layer partition, and stipulates the cable direction and the pipe diameter utilization rate of each zone, thereby facilitating the division of the line and avoiding the line. The winding or knotting of the cable requires that the cable box wiring device be provided at each cable joint to ensure the safety and maintenance of the line.
本实用新型解决其技术问题所采用的技术方案是：在线管内壁采用2分区或3分区或者4分区的形式，根据线管的内径大小，计算管径利用率设置分区，布线中根据线缆的横截面积区分采用几分区的对应型号线管。线管内壁分区采用的材料和线管采用的原料是一体的，均为阻燃绝缘材质，生产时经过挤塑成一个整体，使得穿线线路固定。阻燃绝缘内壁分隔区设计为光滑弧形分隔，最大的利用管径利用率，使得线缆穿线和抽取换线阻力更小，更易抽拉线缆，不损伤线缆。 The technical solution adopted by the utility model to solve the technical problem is that the inner wall of the online pipe adopts the form of 2 partitions or 3 partitions or 4 partitions, and according to the inner diameter of the conduit, the pipe diameter utilization ratio is set and the partition is arranged according to the cable. The cross-sectional area is divided into corresponding models of several sections. The material used in the inner wall section of the line pipe and the raw materials used in the line pipe are integrated, all of which are flame-retardant insulating materials, which are extruded into a whole during production, so that the threading line is fixed. The partition wall of the flame-retardant insulation inner wall is designed to be smoothly curved and separated, and the maximum utilization of the pipe diameter makes the cable threading and the extraction line resistance less, and the cable can be pulled more easily without damaging the cable.
本实用新型的有益效果是，可以在有效规避线缆穿线中缠绕或打结等现象，有效规范线缆穿线的路线，使每根穿线线缆互不影响，相互独立，真正做到保护线缆，方便维护的效果。The utility model has the beneficial effects that the utility model can effectively circumvent the phenomenon of winding or tying in the cable threading, effectively standardize the route of the cable threading, so that each threading cable does not affect each other and is independent of each other, and truly protects the cable. Easy to maintain the effect.
