An instrumentation cable is a type of cable used to transmit electrical signals between devices in various control and measurement applications, such as in process control systems, power generation, and communication systems. These cables are designed to be highly resistant to electromagnetic interference and provide stable and reliable transmission of signals over long distances. Instrumentation cables typically have multiple insulated conductors with shielding and are available in various configurations, including screened and unscreened, armored and unarmored, and multi-core cables. They are widely used in industrial applications to connect various sensors, actuators, and control systems for accurate and reliable data acquisition and transmission.
仪表电缆是一种用于在各种控制和测量应用中的设备之间传输电信号的电缆，例如在过程控制系统、发电和通信系统中。这些电缆的设计具有很强的抗电磁干扰能力，能够长距离稳定可靠地传输信号。仪表电缆通常有多根带屏蔽的绝缘导线，有多种配置可供选择，包括屏蔽和非屏蔽、铠装和非铠装以及多芯电缆。它们广泛用于工业应用，连接各种传感器、执行器和控制系统，以实现精确可靠的数据采集和传输。

COLOUR OF DIELECTRIC:-
Cores are identified with a different type of color scheme as per requirement as below:-

i) BS EN 50228, BS: 5308 – I & II,
ii) As Per IEC, ITD or number Printing.
iii) As Per Customers Scheme.

电介质颜色:-
根据以下要求，用不同类型的配色方案来识别芯

i) BS EN 50228，英国标准5308 – I和II，
ii)根据IEC、ITD或数字印刷。
iii)根据客户计划。

Core/Pair Identification :-
Multi-Pair Cables :
The cores within a pair are identified by one of the following methods :
• By printing a reference code on one insulated conductor, or both of them, that indicates the number of that single pair.
• By a numbered non – hygroscopic tape applied over the pair.
• By using different colour combinations to uniquely identify the pair.
核心/线对识别:-
多线对电缆:
一对内核通过以下方法之一进行识别:
通过在一根绝缘导线或两根绝缘导线上打印参考代码，表明单对导线的编号。
通过在线对上贴上编号的不吸湿胶带。
通过使用不同的颜色组合来唯一识别该对。

PAIR/TRIAD/QUAD :-
In cables which make up a pair, triad or quad core wires are uniformly twisted together. Maximum lay length determined by customer needs and minimum crosstalk requirements is up to 80mm .
一对/三对/四对:-
在组成线对的电缆中，三芯或四芯电线均匀地绞合在一起。根据客户需求和最小串扰要求确定的最大捻距可达80毫米。

INDIVIDUAL SHIELDING：
If required, Individual Shielding may be of Poly Aluminum [Thin Layer of Aluminum Foil bonded to Polyester Film] Tape with Annealed Tinned Copper Drain Wire. It prevents the shorting of adjacent shield and minimizes the cross talk and ground loops. A Tinned Copper drain Wire is installed to provide continuous contact with the shield and allow for connection to ground. Tinning the drain wire reduces galvanic corrosion between drain and shield.
单独屏蔽：
如果需要，单独的屏蔽可以是带有退火镀锡铜加蔽线的聚铝[粘合在聚酯薄膜上的铝箔薄层]带。它可以防止相邻屏蔽层短路，并将串扰和接地环路降至最低。安装镀锡铜加蔽线以提供与屏蔽层的连续接触，并允许接地。给排扰线镀锡可以减少排扰线和屏蔽层之间的电偶腐蚀。

LAYING OF PAIRS/TRIAD/QUAD：
Pairs/Triads/Quads are laid up with suitable lay. The outer most layers are right hand lay and successive layers are laid up with opposite lay. Then, a Melinex Tape is provided to bind up laid up Pair/Triad/Quad.
线对/三线组/四线组的铺设:
线对/三线组/四线组以合适的捻距排列。最外层是右手捻，连续层与相反捻合。然后，提供一条Melinex胶带，用于捆扎成对/三股/四股电缆。

OVERALL SHIELDING：
Overall shielded cable constructions are recommended for use in Instrumentation computer and control application where signals are transmitted in excess of 100 Mili volts except in areas where high voltage and current sources create excessive noise interference. If required, Overall l Shielding may be of Annealed Tinned Copper Braiding/Poly Aluminum [Thin Layer of Aluminum Foil bonded to Polyester Film] Tape with Annealed Tinned Copper Drain Wire. Braiding ATC Shield has high tensile Strength and provides better coverage in flexing application. They are easier to terminate. This provides effective shielding; cross talk and noise are kept to an absolute minimum.
整体屏蔽:
建议将整体屏蔽电缆结构用于信号传输超过100毫伏的仪器、计算机和控制应用，除非高压和电流源会产生过多的噪声干扰。如果需要，整体l屏蔽可以是退火镀锡铜编织/聚铝[粘合到聚酯薄膜上的铝箔薄层]带和退火镀锡铜加蔽线。编织ATC屏蔽具有高抗拉强度，并在弯曲应用中提供更好的覆盖。它们更容易终止。这提供了有效的屏蔽；串扰和噪声被保持在绝对最小。

INNER SHEATH：
The laid up pair/triad/quad after shielding are provided with an inner sheath, which may be either Extruded Inner Sheath or wrap with PVC Tape.
内护套:
屏蔽后的绞合线对/三线组/四线组配有内护套，该内护套可以是挤压成型的内护套，也可以是用PVC胶带包裹的。

ARMOURING：
It is applied over inner Sheath. It may consist of galvanized Round Steel wires or galvanized Flat Steel Strips. Steel wire armoured cables are suitable for direct burial. One or more copper wires can be incorporated in the armour to increase the conductivity of the Armour where it is being used as an earth return.
铠装:
它应用在内护套上。它可以由镀锌圆钢丝或镀锌扁钢条组成。钢丝铠装电缆适用于直埋。可以将一根或多根铜线结合到铠装中，以增加用作接地回路的铠装的导电性。

OUTER SHEATH：
It is applied over Armouring in case of Armoured Wire or over Inner Sheath in case of Unarmoured Cable. The Color of Sheath is Black,Grey or as per customer’s choice.The cable jacket is resistant to sunlight, moisture and vapour penetration. The Sheath material may be General Purpose PVC, FR / HR / FRLS PVC / Low Smoke Zero Halogen Compound as per requirement of the specification.The choice of sheathing materials to be used for any application is dependent on :

• Temperature
• Flexibility
• Electrical characteristics
• Smoke and acid gas emission limitations
• Resistance to chemicals
• Water resistance
• Exposure to UV

外部护套:
如果是铠装线，则涂在铠装层上；如果是非铠装电缆，则涂在内护套上。护套的颜色为黑色、灰色或根据客户的选择。电缆护套耐阳光、湿气和蒸汽渗透。根据规范要求，护套材料可以是通用PVC、FR / HR / FRLS PVC /低烟无卤化合物。用于任何应用的护套材料的选择取决于:

温度
灵活性
电气特性
烟雾和酸性气体排放限制
耐化学品性
防水性
暴露在紫外线下

RIP CORD：
To simplify jacket removal, high tensile strength nylon Rip Cord is provided over laid up of pairs/triads/quads below the outer sheath in case of Unarmoured cable or below the Inner Sheath in case of armoured Cable.
撕裂线:
为了简化护套拆除，在非铠装电缆的外护套下方或铠装电缆的内护套下方，在双绞线/三芯线/四芯线的叠层上提供高抗拉强度尼龙撕裂线。
