该应用程序根据您输入的设计数据和所选选项计算所需的电缆尺寸。根据 BS 7671 IET 接线规则，计算各种电缆类型和尺寸、保护装置、安装方法和修正系数所需的最小电缆尺寸（以 mm² 为单位）。
您可以使用此电缆计算应用程序检查现有电缆和电路的合规性，以验证现有电气安装中的电缆尺寸，或在新安装中设计新的最终电路和子主电源，并创建和保存计算结果的 PDF 文件。
特点：
✔ 打印电缆计算结果
✔ 验证和确认检查
✔ 支持制造商特定的 MCCB 和 ACB（最大 Z）
✔ 支持 TT 接地系统中的 RCD
设计参数：
- Ib：设计电流（安培）
- L：电路长度（米）
- Vd：最大允许电压降 (%)
- Uo：电源电压（伏特）
- Ze/Zdb：电源接地回路阻抗（欧姆）
- In：保护装置额定值（安培）
- s : 最大断开时间（秒）
- 电缆类型
- 安装方法
- 防护装置类型
- 接地系统类型（TN-C-S、TN-S、TT）
修正系数：
- Cg：分组
- Ca：环境空气温度
- Ca：环境地面温度
- Ci : 隔热
- 抄送：BS 3036 半封闭式保险丝
电缆计算器计算：
- It : 表格电流
- R1+R2 ：电路预期 R1+R2 值
- Zs ：电路预期 Zs 值
- 最大 Zs：计算的 0.2 秒、0.4 秒和 5 秒最大 Z 值（80% + 100% 值）
- Vd ：计算出的电压降 %
- CF：总应用校正因子值
- 所需的最小电缆尺寸（mm²）
该电缆计算器考虑并应用以下因素来计算电缆尺寸：
- Vd：最大电压降
- Cf：修正系数
- L：电路长度
- Zs：最大Zs 80%温度调整值
验证检查示例：
- 使用最大 Zs 80% 值检查计算的 Zs
- 检查用户是否选择 TT 接地系统 = 需要 RCD
- 检查用户是否选择 3% 伏降（照明）且设备 In = >16 安培
- 检查用户是否选择断开时间 5 秒且设备 In = <32 安培
- 检查所选保护装置 Max Zs 是否已超过您的供应 Zs/Zdb 值
- 检查设计电流 (Ib) 是否超过保护装置额定值 (In)
- 检查保护装置额定值 (In) 是否是设计电流 (Ib) 的两倍
- + 还有更多...
一款出色的电缆选型工具，除了所需的最小电缆尺寸之外，还可以计算预期的 Zs 值、电压降 % 和估计的 r1+r2。
如何使用：
1) 第 1 步 - 输入电缆计算设计参数
2) 第 2 步 - 选择安装方法并应用任何相关的修正系数
3) 点击“计算”来计算电缆尺寸
4) 点击打印机图标打印电缆计算结果
5) 可选，签署屏幕以签署文档
此电缆尺寸计算器应用程序专为 Android 手机、平板电脑和基于 Android 的 PC 设计。

I have only had a quick play, and the app itself is fine. What let's it down for me are the following. On opening the app you are greeted with, what I can only describe as a sales pitch for more products, when I open the app, I just want it to open, and not other things that are for sale. This could be me missing something and not the app, but It doesn't seem to have the option to add a logo or company details, which would be nice, and look more professional, as well as changing the colour.

Pro's 1. I like the layout of the app, it is formatted in a logical order. 2. Easy to use, especially onsite for a quick check. 3. App support are very helpful, I had a problem and they emailed me at various times of the day and evening. 4. Like the option to print out a document with the design and circuit data. Cons 1. Can't see an option to save circuit details. 2. Text overlapped on results sheet . However, easily sorted by reducing display font size ( support team solution to this).

Asks for too much data before calculating. It's very difficult to calculate the initial cable size, as it asks for way too much data. For example, it asks for Ze(Impedance) and Protective device rate, when it is not needed. For example, I simply run cable from transformer to the building electrical panel. If you simply need to calculate size of the cable based on kW or Amp total, all these data is not necessary and not needed. The other application from Ettoire Group is much better.

Nice easy to use calculator, would be nice if you could add a separate CPC for distribution circuits but not a deal breaker.

Thanks for your quick respond but I have worked out size of cable myself so It's fine 3 stars for quick respond But not impressed with the App Needs to be more simple.

Its works better than any other app than i have found on here. The only issue is some of the writing overlaps on my phone
Rob White
Been using it for about a month now and it's been brilliant Best cable calc I've found by far

Shame you can only have a cable with same size cpc as live conductor, especially when using swa and want to run a different size separate cpc.
