Which is a good compensation cable company

Compensation cable is one or more pairs of insulated cables with the same thermoelectric potential value as the matched thermocouple within a certain temperature range (including room temperature), which are used to connect the thermocouple and the measuring device,
To compensate for the errors caused by temperature changes at the connection between them and thermocouples, compensation cables are divided into two types: extension type and compensation type.
Product physical picture:

1、 Production execution standards
GB/T4989-94 and JB/T7495-94.
2、 Usage conditions
1. Working temperature:
Heat resistant: available in two types: 200 ℃ and 260 ℃.
Generally used: maximum temperature of 70 ℃ and 105 ℃.
2. Zui low ambient temperature:
Fluoroplastic insulated and sheathed cables: fixed installation at -60 ℃, non fixed installation at -20 ℃.
Polyvinyl chloride insulated and sheathed cables: fixed installation at -40 ℃, non fixed installation at -15 ℃.
3. Allowable bending radius:
a) Compensation cables with copper tape shielding should not be less than 16 times the outer diameter of the cable;
b) Compensation cables of other structures should not be less than 10 times the outer diameter of the cable.
3、 Model and name
1） Compensation cable

Note:
1. For other types of compensating cables such as KC, JX, SC, EX, NC, TX, etc., simply modify the * item of the model, such as EX-G-VV, TX-H-FVP, etc;
2. When the conductor needs to be a multi strand soft core, an "R" should be added after the prototype number, such as TX-G-VVPR;
3. Polyethylene (Y) insulation and cross-linked polyethylene (YJ) insulation compensation cables can also be provided as needed;
4. The shielding layer of compensation cables can also be wrapped with metal strips, such as composite aluminum strips (P3) and composite copper strips (P2);
5. Flame retardant compensating cables should be labeled with "ZR -" before the prototype number;
6. For armored compensating cables, "-22" should be added after the prototype number to indicate steel tape armor; Add "-32" to indicate steel wire armor;
7. Intrinsically safe compensating cables should be indicated with "ia -" before the prototype number.
4、 Specification Range

Note: In the old standard GB4989-85, ordinary grade is represented by B, and precision grade is represented by A.
5、 Other parameter indicators

Ordering Notice:
1. When placing an order, be sure to specify the product model, specifications, conductor type, quantity, etc.
2. According to the agreement between both parties, any length of delivery is allowed; The length measurement error shall not exceed ± 0.5%.
