电缆夹板选择

电缆夹板选择考虑下列众多因素，理想情况下，如果CMP产品可提供以下内容：电缆建筑型，评分和直径，系统设计，支持结构和环境;188博金宝网站下载然后可以提供关于正确类型的电缆夹板的进一步建议，以及特定应用的电缆夹板间距要求。

Cable – What type of cable is being used?

直径

The overall diameter of the cable will allow CMP Products to size the correct cable cleat and calculate the short circuit forces the cable cleat may be subjected to under fault conditions.

Performance

The cable may have fire performance (FR), or Low Smoke & Fume or Zero Halogen (LSF / LS0H / LSZH) requirements that the cable cleat would also have to adhere to.

Cable Type

应考虑电缆是单核还是多核，电压是否低（LV），介质（MV）或高（HV）。

设计 - 电缆管理系统的概述

Mechanical Load

所有CMP电缆夹188博金宝备用地址188博金宝网站下载板都经过轴向和横向载荷测试，这将确保它们能够支撑电缆的重量。

Short Circuit Rating – kA Peak Fault or r.m.s

What is the maximum peak fault (kA) the cable may be subjected to under short circuit conditions? Based upon
指定的电缆可以通过使用标准IEC 61914计算短路额定值，以使最大势力在短路故障期间需要能够承受电缆夹板。

电缆配置 - 形式/平行或三叶草形成？

系统的电缆配置将定义所需的电缆夹板类型;单个电缆夹板，三轴电缆夹板，四射线电缆夹板，或者这可能表明，CMP产品可能需要设计，测试和认证，以适应其客户端的电缆管理系统要求。188博金宝网站下载

Cable Run Length – How many cable cleats are required?

Whilst the spacing requirements for cable cleats will be subject to cable formation, cable diameter, and short circuit rating, the overall cable run length will give the correct number of cable cleats required for the installation. Cable runs that turn through 90° must also be noted as the cable cleat spacing will be reduced throughout these bends. See cable cleat installation page for more information on installing cleats through bends.

扩张

Single core cables expand and contract more due to temperature changes than multicore cables. If the cable is constrained, considerable forces can be transferred to the supporting structure. To allow for this, single core cables are generally “snaked” making slight loops to take up the expansion and contraction. It is also usual to allow some of the cable cleats to move freely and not restrain all cable cleats.
