GB/T 36292-2018Greases for overhead conductors (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify the use of IEC 61394.2011 "overhead line aluminum, aluminum alloy and bare steel strand anticorrosive grease

Claim".

This standard has more structural adjustments than IEC 61394.2011. Appendix A lists this standard and IEC 61394.2011.

The chapter number is compared to the list.

There are technical differences between this standard and IEC 61394.2011. The terms involved in these differences have been passed through the margins on the outer side of the page.

The vertical single line (|) is marked, and Appendix B gives a list of the corresponding technical differences and their causes.

This standard has made the following editorial changes.

--- In order to be consistent with the existing standard system and in line with Chinese usage habits, change the standard name to "Anticorrosive grease for overhead conductors";

--- In accordance with the requirements of GB/T 1.1-2009, in the "Scope" chapter, added "this standard applies to anti-corrosion grease for overhead conductors";

--- Removed references to IEC 61394.2011.

This standard was proposed by the China Electrical Equipment Industry Association.

This standard is under the jurisdiction of the National Bare Wire Standardization Technical Committee (SAC/TC422).

3 Product identification

The marking of the anti-corrosion grease is in the form of theta1Atheta2 or theta1Btheta2, where A and B are the types of anti-corrosion grease.

--- Type A. Generally suitable for cold coating. Such as grease, semi-solid or solid, mainly composed of mineral oil or synthetic oil and thickener (gold

It is a stable mixture of soap or inorganic compound.

--- Type B. Generally suitable for hot coating. For example, petrolatum, semi-solid or solid, mainly consisting of microcrystalline wax and a small amount of mineral oil and

Machine additive composition.

---theta1. Refers to the minimum applicable temperature value of the anti-corrosion grease in the air to protect the wire at 0 °C, see Table 1.

---theta2. Refers to the highest applicable temperature value of the anti-corrosion grease to meet the applicable requirements (to achieve the specified dropping point or high temperature stability), see Table 1.

Example 1. Type 20A150A anti-corrosion grease, minimum applicable temperature (theta1) -20 ° C, maximum applicable temperature (theta2) 150 ° C.

Example 2. Type 40A120A anti-corrosion grease, minimum applicable temperature (theta1) -40 ° C, maximum applicable temperature (theta2) 120 ° C.

Example 3. Type 20B80B anti-corrosion grease, minimum applicable temperature (theta1) -20 ° C, maximum applicable temperature (theta2) 80 ° C.

The anti-corrosion grease supplier shall provide a unique identification for the product and retain the specific component information for inquiry. The component should contain component deviations,

The preservative under the marking should not change before the sale.
